thanks! Given the really low preemption latency/granularity default
(roughly equivalent to 'timeslice length'), and that basically all of my
focus was on interactivity characteristics, this is a pretty good
result. I suspect it will be necessary to increase the default to 10
msecs (or more) to be on the safe side. (Nick has reported a 4%
kernbench drop so for his kernbench workload it's needed.)
