* mutex.c (pthread_mutex_destroy): Check that the mutex isn't held; invalidate the mutex as early as possible to avoid contention; not perfect - FIXME! * rwlock.c (pthread_rwlock_init): Remove redundant assignment to "rw". (pthread_rwlock_destroy): Invalidate the rwlock before freeing up any of it's resources - to avoid contention. * private.c (ptw32_tkAssocCreate): Change assoc->lock to use a dynamically initialised mutex - only consumes a W32 mutex or critical section when first used, not before. * mutex.c (pthread_mutex_init): Remove redundant assignment to "mx". (pthread_mutexattr_destroy): Set attribute to NULL before freeing it's memory - to avoid contention.
