Previous 'version' is at [1], but this one is vastly expanded, so I didn't really bother keeping count. Anyway, all this started with me breaking core-scheduling [2] and then trying to fix it all up. Because holidays, this all got delayed, and then TJ had a few patches fixing core-sched for ext [3] (which, if/when this lands, can be simplified again). Anyhow, these patches survive both Aaron's test case [4] and Prateek's [5].
