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

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.
