Async cancellation points get activated only when the number of threads are
greater than 1, which is why you're seeing the behaviour you see. What is your
use case anyway? I don't see why something like this should be needed at all.
Of course, I couldn't find anything in the posix definition of pthread_cancel
to not allow something like this:
