    With the new clocksource code, we can (currently just i386, but the
    architecture is generic and I'm working on the other arches) make use of
    continuous clocksources for accumulating time instead of having the deal
    with the problematic PIT (as well as the lost ticks issue).

    Maybe I'm missing what you're proposing, but I think "that pit of
    madness" can now be avoided. :)
