I agree.  The only question is how dire the warnings should be.

I'll answer that question with another question:  Are we going to make
the standard library robust against asynchronous exceptions?  For
example, class Thread has an attribute __stopped that is set using
code similar to the example code I posted.  An exception at just the
wrong time would kill the thread while leaving __stopped == False.

Maybe that particular case is worth fixing, but to find and fix them
all?  Better to put strong warnings on this one method: may cause
unpredictable brokenness.
