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.
