PatchSet 10437 
Date: 2008/01/27 07:46:09
Author: adri
Branch: s27_adri
Tag: (none) 
Log:
Don't go through the userhash/sourcehash logic if we don't need to.

This saves on an inet_ntoa() call (and thus drops the amount of times
we're calling vfprintf() in the main loop); I did similar stuff to userhash
just to be consistent.
