Done, by the way: should be good enough (reduced overhead for non-numa
system from ~1MB to ~16kB).

I'd like to make the allocation search smarter at some point: avoid
exhaustive search of all viable heaps by instead have empty heaps point at
the next heap to try (with some tradeoff between accuracy of guidance and
cost of maintaining the guidance info; I have some ideas here).
