One caution: there is a significant body of software that instead of
using access() does it's own permission checking based on testing the
UID of the file and the Unix mode bits.  So if your Unix UID doesn't
match your AFS uid, subtle things break.  It's not major, but you'll
save yourself some pain if they match up.
