It allows the work to be distributed on both processors. I have used it for buildworlds on freebsd 4.7 and 4.8 builds without a problem. Perhaps it depends what OS version you are using.. maybe 5.x has problems? In any rate, it works and is faster on my single processor 1.2 gig celeron with 256mb ram. (almost twice as fast actually) I follow the handbook during builds.
