    Picking a timer tick is a bit like picking the color of a
    window. Everybody has an opinion and there is no truly "right" choice.
    I guarantee you whatever you pick, someone will come along and say:
    why not X instead?

    A power-of-2 value obviously makes it easy to divide by HZ.

    Robert> More importantly, can we change to 1000?

    On ia64, you can make it anything you want. User-level will pick up
    the current value from sysconf(_SC_CLK_TCK).
