The cache management traffic is definitely an issue. That's where
something like MONITOR/MWAIT could help a lot, or even just a PAUSE
instruction.
We could conceivably get a lot more sophisticated but at least for now
perhaps we should just stick with a PAUSE instruction. I'll add one
to the contention path in lwkt_switch().
