Turning this on on a SMP machine will result in approximately a 4.2% loss of performance (buildworld) and approximately a 5% reduction in power consumption (when idle). Add XXX note on how to really make hlt work (send an IPI to wakeup HLTed cpus on a thread-schedule event? Generate an interrupt somehow?).
