Yes, the socket bug in pl8 is rather dumb, and I too feel pretty dumb that
it's been in the most recent version for so long, but that code has already
been rewritten for pl9.  (It both fixes the duping bug and the you-can-kill-
other-people's-connections bug).  Before you ask if I can post a patch to
the mailing list, I'm afraid I can't because the changes were somewhat
fundamental and are spread througout various files - I'd be afraid of what
would happen if people tried plugging it in on its own.

If you're running a pl8 MUD, you can fix the disconnection bug just by going
into comm.c and searching for "sanity" (I think it's at the end of
comm.c's close_socket()) and deleting or commenting out the little loop at
the end that d/c's people with the same IDNUM as you.  Of course this opens
up the duping bug again - but if you want *both* bugs closed, wait for pl9
or write it yourself. :-)

Best regards to all,
