Hi,
No big changes, this one takes some of the steepness out of the
timeslice curve and fixes a bug with child priorities which
might or might not help startup times. Probably no point doing
any benchmarks on it if they've been done on v7.

It seems to be better than v7 here without X being reniced,
however renicing X to say -10 always seems to help.
