    Well, that just means we need to check for things bound to a subset when
    we fork it off. ie if we have cpus 1,2,3,4 ... and there is

    A bound to 1
    B bound to 2
    C bound to 3
    D bound to 4

    Then when I fork off exclusive subset for CPUs 1&2, I have to push A & B
    into it. You're right, what I said was broken ... but it doesn't seem
    hard to fix.
