    That's no different than what can happen today -- if a task actually
    is in an 8 node cpuset, sets up its mempolicies accordingly, and then
    gets shoe horned into a 4 node cpuset.

    It's not good or bad; it's just interactions between two mechanisms.

    If your app doesn't run well in a small cpuset, don't run it there
    (or do run it there, poorly ;).

    I won't rest till it's the best ...
