Did you guys miss the point that he only used -j64 to try to load the system in a way that would normally result in terrible user interactive desktop perfromance, and test that the new cgroups hack causes the desktop and other user interactive processes to get cpu and i/o scheduling no matter how loaded the rest of the system is?

No, I didn't. If you start swaping, the cpu stress point is missed, because you get into the disk i/o stress point. The system will become unresponsive for a different reason and you can't see if the new scheduler is working slow because the patch doesn't work or because it is waiting for the disk.
