Yikes! No!!!! There are good reasons why users should be able to set
the uid/gid bits on files they own (remember: set-uid is set to the ID
of the *owner* of the file, not necessarily set-uid to root).
This whole thread is getting ridiculous! People are beginning to
suggest disabling legitimate features left, right and centre!
Let's be a little more creative. Please.
