I belive there is only one lock (the dispatcher lock) on Windows (<= 
XP). On W2K3 there is one other lock in KPRCB because the dispatching 
structures were moved there and they're per-processor now. The 
per-processor idle thread then moves threads from other processor's 
queue AFAIK. Please correct me if I'm wrong.

P.S. The thread dispatching that is currently in Ps should be moved to Ke.
