It does.

It does.

That's one of the reasons why linux's interactive behaviour is really
pretty good even under load. If I've got a large simulation plus a
compile going on in the background, response time in interactive
sessions is still instantaneous.

It might be possible to improve the scheduler a bit, but I haven't
seen any evidence that we need to.

Cheers,
Stephen.
