I've made some small changes, which are in fix-acls2.  What I need to do
with you is hook up gpfs to the new non_posix_acls helper functions I've
written.  (I decided against the change we discussed, to avoid needing
to call stat at both layers). 

The blob you get from gpfs is the acl_as_blob argument.

Anyway, we should probably do some of this interactively, let me know
when you have time. 

When this is all finished to your satisfaction, we can probably squash
some patches as well.
