It's certainly a good idea, but doesn't really address my worry.  The
minor performance impact is not what bothers me most.  It's the fact
that in the common case the result of these calls are discarded.
That's just plain ugly, IMO.

My preferred alternative would be a mount option.  Amir, Alex, would
you both be okay with that?
