	* 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.
