I have some patches locally that basically let you give out a small set of nodes initially to a cpuset, and if memory pressure in try_to_free_pages() passes a specified threshold, automatically allocate one of the parent cpuset's unused memory nodes to the child cpuset, up to specified limit. It's a bit ugly, but lets you trade of performance vs memory footprint on a per-job basis (when combined with fake numa to give lots of small nodes).
