CVS commit: [nathanw_sa] basesrc/lib/libpthread

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

Module Name:    basesrc
Committed By:   nathanw
Date:           Tue Oct 22 21:56:01 UTC 2002

Modified Files:
        basesrc/lib/libpthread [nathanw_sa]: pthread_mutex.c

Log Message:
Speed up pthread_mutex_unlock() similarly to what was done to
pthread_mutex_lock(): heavily optimize for the case of a mutex with no
waiters, and defer the waiter case to a separate function.

Uncontested mutexes now no longer use library spin locks.
