There seem to be several problems with this patch. I would have sent
this as a personal reply; but one of the problems is serious.
1) A pipe to the "w" command is opened using "popen", but I don't
see the corresponding pclose().
2) Screen is usually installed as set-uid with owner root (e.g.
to be able to call chown()). Thus the "w" command must be
started in a child process which properly resets it's uid
(similar to the way the "hardcopy" files are created).
