In a SLIME buffer, type in , (comma). You're placed in the minibuffer and SLIME asks which command to execute. Type in sayoonara and hit Enter. You should see SLIME exiting, the minibuffer mentions that "Connection closed." and you're placed in the *scratch* buffer.
According to the manual page on this, "once save-buffers-kill-emacs is finished with all file saving and confirmation, it calls kill-emacs which runs the functions in this hook." So the check for active processes is done before the hook is called.
Place your cursor inside the 'slime-smart-quit routine and type M-x edebug-defun. Then exit Emacs as you normally would. You should then be prompted by the Emacs lisp debugger edebug. It's a pretty easy debugger to use (type ? for help).
I use it for all repl-like buffers that I have, which includes octave, python, scheme, shell and haskell's ghci. So far nothing bad happened when these repls get killed silently so I assume this solution isn't bad though may not be graceful.
Here's what I feel is a better solution that specifically ignores only SLIME buffers. It doesn't actually kill the processes if the user aborts the kill-emacs command, nor does it require waiting for slime to asynchronously exit gracefully.

Tonight, the observations bothering me is a slime mold. I am looking through pages of other slime mold observations, trying to find the nearest match. The problem is, of the ones that look most like mine, some are identified as a rarely-observed species, and others are not identified to species. Complicating this, there is a very commonly-observed species which at some stages looks kind of like mine, although most observations of it are at a stage that does not.
One of the problems with identifying even the common species is that they change shape and colour as they develop and progress from the plasmodium to the fruiting body stage. If people post only one photo that captures one moment in the development of a slime mould, it makes it very difficult to identify.
I was unable to identify your photo of the plasmodium. Identifying myxomycetes at the plasmodial stage is a bit like expecting people to identify plants from a photo of their roots.
I identified your observation of Fuligo septica. F. septica is probably the most common myxomycete observed on iNat. I do not spend a lot of time identify the species as it is one that other people can easily identify.
The bubbling action is caused by a thin layer of baking soda at the bottom of the sensory tub. With the slime at just the right consistency, it slows down the reaction between the vinegar in the slime and the baking soda at the bottom of the tub. For us, they kept reacting for at least 24 hours! My son was super impressed by that one, and it was a great way to observe baking soda and vinegar reaction over a long period of time.
IT IS SPRING IN HOUSTON, which means that each day the temperature rises and so does the humidity. The bricks of my house sweat. In my yard the damp air condenses on the leaves of the crepe myrtle tree; a shower falls from the branches with the slightest breeze. The dampness has darkened the flower bed, and from the black mulch has emerged what looks like a pile of snotty scrambled eggs in a shade of shocking, bilious yellow. As if someone sneezed on their way to the front door, but what came out was mustard and marshmallow.
Here in this little patch of mulch in my yard is a creature that begins life as a microscopic amoeba and ends it as a vibrant splotch that produces spores, and for all the time in between, it is a single cell that can grow as large as a bath mat, has no brain, no sense of sight or smell, but can solve mazes, learn patterns, keep time, and pass down the wisdom of generations.
Perhaps a limit of our so-called intelligence is that we cannot fathom ourselves in the context of time at this scale, and that so many of us fail, so consistently, to marvel at any lives but our own. I remember a recent visit to the Morian Hall of Paleontology at the Houston Museum of Natural Science. I moved with the exhibit through geologic time, beginning with trilobite fossils from more than 500 million years ago, toward creatures that become larger and more terrifying before each of five extinction events, in all of which climate change has been a factor. Each time, millions of species have disappeared from the planet, but thanks to small, simple organisms, life has somehow carried on.
Slime mold might not have evolved much in the past two billion years, but it has learned a few things during that time. In laboratory environments, researchers have cut Physarum polycephalum into pieces and found that it can fuse back together within two minutes. Or, each piece can go off and live separate lives, learn new things, and return later to fuse together, and in the fusing, each individual can teach the other what it knows, and can learn from it in return.
Lacy M. Johnson is the author of several books, including the essay collection The Reckonings, and is coeditor of More City than Water: A Houston Flood Atlas. She teaches at Rice University and is the founding director of the Houston Flood Museum.
The slime mold has a peculiar pattern which looks like a polygonal structures common in processes that bring about a transfer of a diffusive parameter transport; for instance, lava flow polygonal columns, fairy circles , and so on. I am thinking if this is the case for those old mazes, does no it?
To start, Dr. Johnson might want to read up on crape myrtles. Those drops are released from aphids feeding on the plant, bug poo. Otherwise, I enjoyed the read and learned a good bit about slime molds. Thanks for the time & effort needed to put this together.
A fascinating article; thank you! I find the descriptive common names of the slime molds interesting, and the endurance of the organism to be mind boggling. I will not be looking at molds the same way as I did before reading this article.
What a delightful read! I am in love with slime mold anew! Also, it is nice to know that I have a soulmate living in my city! Thank you so much Mrs. Johnson, reading your article made me feel happy without reason!
The piece is entertaining, illuminating, even inspiring. Even though I bring to bear degrees in Geology (Yale), Geochemistry (Rice) and Nuclear Geochemistry (Yale) I am humbled by intricate nature and longevity of the slime mold and the Zen-like piece by Ms. Johnson. Although I grew up in Houston, which seems likes it would be a favorable habitat for such a creature, I have never heard of one before and certainly not with the combination of science and poetry presented here.
The persistence of the slime mold gives me hope that global catastrophes are survivable. Before giving up on the idea that there is a hierarchy in evolution, however, I would like to note that it was Ms. Johnson who wrote about the slime mold and not the other way around.
Thank you, very interesting to read, many topics pass.
For my own interest: since I (seem to have) started a discussion with a family member who has studied molecular cell biology in the past, I would like to ask for your opinion on where or how live (living organisms) started to exist. I think viruses are key, what do you think?
Enjoyed the article very much. There seems to be intelligence at least in this one person (the writer) which is refresshing to find. I have known about slime molds for some time, though never have taken the time to study them thoroughly. I have wondered how they make decisions without seemingly any centralized structure. And now I see how they are capable of going into a static state until favorable conditions arise. This is something humans like Timothy Leary and others would love to do, to never have to die. Yet, is far beyond our capacities. I bow to the slime mold.
Also, as a radical anarchist activist of many years, I am in most cases against hierarchies and have made a 7 minut animation that explains horizontal governing which is virtually incorruptible: =wywMhg604W8&t=5s
Truly brilliant writing and illuminating information in this exciting, thought-provoking article. Thank you for inspiring further research on my part and giving a strong (if ephemeral) realignment of perspective !

I love the way these look. They color and transparency changes as they dry and they are really easy (albeit messy) to make. So the next time you make slime set some chucks of different colors aside and turn them into galactic art!
What I love about this project is the two in one nature. You can start by simply making slime with your kids, which is a guaranteed boredom buster, and then use some it to make something lovely for your window. This would be a great double whammy project for the summer time.
