CVS commit: src/lib/libpthread

Module Name:    src

Modified Files:
        src/lib/libpthread: pthread_lock.c

Log Message:
Drop PTHREAD__NSPINS back from 1000 to 64. Setting the waiters bits and
preparing to sleep on a mutex are slow in relative terms, so this allows
us to recover from short lock holds without blocking, while not wasting
too much time on longer holds.
