Do you really not get "Waiting for critical tasks to finish before terminating program"? That would mean your signal handler isn't called at all.

Either way, I already gave a reason the current code won't always work. Executing the signal handler will prevent (at least) that thread from doing anything else. If the signal handler is called from a thread1 thread, that thread1 thread won't be able to progress.
