    I agree. I have seen really fabulous system response since Rik's
    changes were merged in.
    I have managed to crash my machine a couple of times (I am working on
    getting a
    serial debugging connection set up, since I don't see any OOPS
    messages), but I think this
    is not terribly surprising. My impression is that system responsiveness
    is much improved.
    Let's hang in there a bit longer. We are making rapid progress on
    testing and fixing.
