Nobody gets a cpu number just to get a cpu number - it's not a useful
thing to benchmark. What does getcpu() so much that we care?

malloc is the primary target I believe. Saves lots of memory to keep
caches per CPU rather than per thread.

Also improves locality; that does seem like a good idea.  Has anyone
written and tested the corresponding changes to a malloc implementation?
