    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).
