What I really want is for files *created* in a directory to inherit a
certain set of permissions, the way they inherit ownership if the
directory is ug+s.  I could do this with a cron job but of course there
would be some lag period between the time the file is created and the
time it is assigned the correct permissions.  I wouldn't want to run the
cron job too frequently because it would be at least mildly disk
intensive having to spider through the whole directory structure.

I have a suspicion that this is what the new ACL filesystem features in
2.6 do, but a quick look at the documentation was unenlightening.
