I expect that with the node-local allocations you're not getting
a lot of benefit from the lock amortisation. Anton will.
It's the lack of improvement of cache-niceness which is irksome.
Perhaps the heuristic should be based on recency-of-allocation and
not recency-of-freeing. I'll play with that.

Well, it's all in the noise floor, isn't it? Better off trying
broader tests. I had a play with netperf and the chatroom
benchmark. But the latter varied from 80,000 msgs/sec up
to 350,000 between runs.
