Initial testing on my NUMA box looks good. So far, I only have
kernbench numbers, but the system time shows a nice decrease,
and the CPU % busy time has gone up.

Kernbench:
Elapsed User System CPU
ingoD7-59 28.944s 285.008s 79.998s 1260.8%
stock59 29.668s 283.762s 82.286s 1233%

I'll try to get more testing in over the next few days.

There was one minor build error introduced by the patch:

#define NODE_THRESHOLD 125

was removed, but the NUMA code uses this.
