**

|
** 2) another user far away logs in normally with the nick
|

** "foobar" (quite legal, as this server didn't propagate
|
|
** it).
|
|
** 3) now this server gets nick "foobar" from outside, but
|
|
** has alread the same defined locally. Current server
|
|
** would just issue "KILL foobar" to clean out dups. But,
|
|
** this is not fair. It should actually request another

** nick from local user or kill him/her...
