Those incidents are most probably unrelated to the issue discussed in
this bug, because the timer thread was introduced into Emacs only very
recently, it does not exist in Emacs 24.2 and earlier.

That is so vague I cannot even begin thinking about what you have in
mind.
In any case, what Andrew reported looks like some thread is suspended
_while_ it holds a critical section. So, if anything, this is not
about lack of critical sections usage.

Thanks, I see.

I am not sure of that ;-)
What is suspending the thread? Should it be able to do that?

I've been running an (unpatched) emacs-24 r110867 build for a few hours, and so far it seems to be behaving well. I'll report back after a longer run to see if the lockup can be still be reproduced.

I rebuilt emacs-24 at r110874 this morning, and have not seen any freezes or lockups all day. I think this bug can now be closed.
