I'm not sure now that my memory is not corrupt :) but I think that a
code like:


Called from different threads could put the thread in a dumb state
where it is suspended but it can not be resumed due something like a
resume arriving after the suspend has been started, but not finished,
so I think it is only "safe" using critical sections.
