Except under NT there is both a "read-only" bit AND the possibility of
excluding write access via ACL's.  As far as a predicate for removing files go
(eg) you would probably only want to test for the read-only bit.  You can still
delete a file that is not writable under NT (you can deny Delete access
separately from Write access).
