I guess I'm saying 'no'
also if you do then a file that is in teh directory before the flag is set is
treated differently to one that is created afterwards, and one that is created
in s subirectory that was created before the change is also treated differntly
(because the subdir doesn't have the flag).
I think the dumpper should be fixed to not dump files that are further along the
file hierarchy
than a directory that has the bit set..
