The problem here is that there is an unavoidable race between the bridge 
sending a
QUIT to IRC, and IRC sending a message which references the nick who just left. 
 I'll
think about how to best resolve this.

I rewrote a lot of the nick-related stuff for InspIRCd a few months back.  As 
far as I 
know, this issue has been fixed for a while.
