[cod] 1.41d ... server CPU load fixes.

[Peter Schwartz]

Good Work on the Patch. Thanks guys.

Just on another note, currently my server is a p42.6 with 1 Gb of RAM, on 
the server with about 12 ppl, the CPU usage is at 40-65% usage. We are 
currently going to upgrade, but would a duel xeon machane make a difference, 
and will it use both processors?

Cheers
Elmo
