The problem is that sometimes SIG_UNBLOCK does not immediatly call the pending signal, but it calls it "later". The problem is that I don't know exactly when. I tried to wait the pending signal using signal.pause(), but I got a bus error!?

Example of the problem:

pthread_sigmask(SIG_BLOCK, [SIGUSR1])
os.kill(os.getpid(), SIGUSR1)
pthread_sigmask(SIG_UNBLOCK, [SIGUSR1])
