OK, I'll keep that in mind. I now have most votes for
a separate SCHED_IDLE policy.

But about the multiple-vs-single queue, Linux is better off
with just two queues, one for RT and one for the rest.

I'm currently running a single-queue system with a load of
100+ (100 CPU loops running at nice 0!) and the system remains
very much responsive... On a P100!

X11amp seems to skip a beat every now and then, however ;)
