Now that this set has hit the mainline I just wanted to chime in and
say this makes a big difference. Under my current load (a parallel
kernel build and virtualbox session the old kernel would have been
totally unusable. With Linus's current bits, things are much better
(still a little sluggish with a big dd going on in the virtualbox, but
actually usable).
