the issue is *runnable* tasks. do your machines routinely report loadaverages of 1000? if so, I'm impressed!
the issue here is whether someone can come up with a maintainable scheduler that has the requisite performance. since the runqueue is normally short, the scheduler's performance function must have a very small constant term. if it's true that there are applications that result in long runqueues, then the performance curve needs to be as flat and horizontal as possible, again, without degrading the constant term.
AFAIK, loopback volanomark does not resemble _any_ real application.
