That's not quite my point. Having the acl's stashed in-memory should be
measured against storing them on-disk; if variably sized, you'll fragment
kmem, and if fixed-size, you may end up using twice as much memory for
acl-attached vnodes. It *might* be more useful to fetch the ACL data on an
as-needed basis, based on that.
(Just a suggestion.)
