I've also seen it in functionally similar, but more complicated,
situations.  For example: a user wants to do his editing on a
Windows box, but doesn't have WinCVS set up.  So he:
 1. does a "cvs update" in his sandbox on the UNIX server
 2. FTP's the sandbox to his desktop machine
 3. edits the desktop copy of the sandbox
 4. FTP's the sandbox back
 5. commits (with possible updates and merges of course)
At least that's what he does in theory.  If he gets the
sequencing wrong, he'll clobber either other users' changes (by
doing 2 before 1), or his own (by doing 3 before 2).

So be imaginative in looking for ways that users could be
doing stuff behind CVS's back to screw things up.

(Of course, there are possible linebreak-translation problems,
too, if someone does things as described above...)
