The atexit docs (http://docs.python.org/library/atexit.html) are very
confusing. In one place they say, "The order in which the functions are
called is not defined". In another place, "all functions registered are
called in last in, first out order". Which is correct?
Also, it's not clear how atexit handlers interact with threading. Do
all handlers get called in the main thread? What if some other thread
registers a handler? Does it get called in that thread?
confusing. In one place they say, "The order in which the functions are

Check the tracker (bugs.python.org) for atexit issues, open and closed.

I believe there was one about order and whether to make a guarantee. The
doc might have been changed one place and not another. The newer
statement is probably correct. In any case, the wrong place should be
corrected.
