 I think the code should just keep invoking the handler for
 all unmasked signals:
 
 	while (SIGNOTEMPTY(sigset)) {
 		for (i = 0; i < NSIG; i++) {
 			if (sigismember(...)) {
 				_thread_sig_invoke_handler(...)
 			}
 		}
 		/* restore mask */
 		/* recalculate pending deliverable signals in sigset */
 	}
