The following patch to find will only allow users to see the files to
which they have search permission.  Of course the database is still there,
readable and all, so people could read it directly.  I you are that
paranoid, make find setgid to daemon, and allow only group daemon access
to the database.  this wouldn't harm updatedb, since it is run as root.
