    Of course, if this is the case, the question will be raised. But as a
    general rule, I don't see much potential in O(1) to finely tune scheduling
    according to several criteria. In O(logN), you can adjust scheduling in
    realtime at a very low cost. Better processing of varying priorities or
    fork() comes to mind.
