Known bug with OpenBSD pthreads. A sleeping thread will not get signaled until it wakes for some other reason. In the test program main is sleeping in the call to pthread join. It won't see any signals until thr1 exits. If you enable interrupts in thr1 the program will terminate as expected. Don't call printf from signal handlers. /\/\arc
