I've made a (very small) change to goodness() in
linux/kernel/sched.c to make the current scheduler
more resemblent of the QNX scheduler, but without
the problem of deadlocks.
I've done some testing, and it seems to make Linux's
interactive response just a little bit snappier.
But it might have some side-effects in other (exotic?)
situations, so I'd like to see it tested before sending
it to Linus.
Rik.
