  The server isn't working as you would expect it to do... The server takes
the return value from #0:do_login_command at first read() or suspend(), and 
forget about it, ignoring it is still running or not. The point is the
server is written in C, and the protocol between MOO codes is meaningless
to the server.
  I wrote a patch for this purpose before, and you can get it from
ftp://ee.snu.ac.kr/users/jsahn/moo-1.7.9-read.gz, though it breaks
the interface between server and db slightly...

Hope this will help.
