behlendo 4afaaefa05 Implement per-cpu local caches. This seems to have bough me another
factor of 10x improvement on SMP system due to reduced lock contention.
This may put me in the ballpark of what is needed.  We can still further
improve things on NUMA systems by creating an additional L3 cache per 
memory node instead of the current global pool.  With luck this won't
be needed.  I should also take another look at the locking now that
everything is working.  There's a good chance I can tighten it up a
little bit and improve things a little more.
