Since hyperthreading shares some parts of the processor but not all, well depending upon the operations being executed by each you could end up with one thread on the "real" processor blocking one on the "fake" processor because one is using a common resource that the other needs. I think the real question here is, /why/ are you asking? :) -- _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
