    At the request of Jeremie Le Hen, I've inserted 5.x-STABLE UP and SMP
    numbers below.

    5.x UP 76 131 66 65 66 65 4.00 4.45
                 75 133 67 66 67 66 4.06 4.50

    5.x SMP 75 133 67 66 67 66 4.00 4.45
                 74 135 68 66 68 67 4.11 4.56

    This would seem to place it closer to 4.x than 5.x -- possibly a property
    of a lack of preemption. Again, the differences here are so small it's a
    bit difficult to reason using them.
