	Why ? ;-) it's obviously the best thing to do.

	Hmm - 'access' is a 'stat-like' operation I believe, either way - on a
slow / remote nfs mounted file-system [ still using file-method ], it's
extremely worthwhile to be able to reduce the round-tripping to a
minimum. I believe each access call is a roundtrip - but could be wrong.

	Yes; that's prolly what I was trying to say ;-)

	Yep; adding GET_ACCESS_RIGHTS is prolly best.
