[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    basesrc
Committed By:   nathanw
Date:           Mon May 20 19:18:45 UTC 2002

Modified Files:
        basesrc/lib/libpthread [nathanw_sa]: pthread.c pthread_cancelstub.c
            pthread_int.h pthread_sig.c

Log Message:
Many signal improvements:

 - Implement sigsuspend()
 - Take pending signals that are unblocked in pthread_sigmask().
 - Tweak the signal mask passed by sigaction() to permit us to manage
   our own thread-specific signal masks.
 - Don't try to deliver signals to zombie threads.
 - Prevent a race between deciding a thread can take a signal and actually
   taking it.
 - Don't put threads that are blocked in a syscall on the run queue.
 - Add debug logging.
