djabberd already has support for writing out a pidfile in the form of a 
"PidFile" configuration directive, but I suppose having it as a command 
line option is useful too.

I don't think the current PidFile implementation cleans up the file when 
DJabberd quits, either; to be honest, I just hacked it in while trying 
to create an init script. :)
