Good to be back and hacking away in earnest. After resyncing with the current kernel I spent a lot of time thinking about the staircase scheduler. I've managed to resolve the remaining corner cases and believe I have a good working design now that seems stable, fair and has good interactivity and responsiveness.

Staircase v6.2 for linux-2.6.7-rc2

Ok now I need to benchmark the crap out of it and get as many testers as possible.
