> We should properly interleave AIO threads (disk threads) evenly across the
> NUMA nodes, and have affinity on those nodes. That would allow for better
> memory distribution across NUMA nodes. We've noticed pretty uneven
> allocations on some boxes, which I attribute to this problem (but no strong
> evidence, but it does make sense).
