231	<	**      (actually it has been implemented already for a while) -orabidoo
232	<	**
233	<	**      1) user telnets in and gives only "NICK foobar" and waits
234	<	**      2) another user far away logs in normally with the nick
235	<	**         "foobar" (quite legal, as this server didn't propagate
236	<	**         it).
237	<	**      3) now this server gets nick "foobar" from outside, but
238	<	**         has alread the same defined locally. Current server
239	<	**         would just issue "KILL foobar" to clean out dups. But,
