More and more it just seems to be a bandaid to the priority inverting spin on waiters, and it does seem to be of detriment to general interacivity. I can now reproduce some loss of interactive feel with O17. Something specific for the spin on waiters is required that doesn't affect general performance. The fact that I can reproduce the same starvation in vanilla 2.6.0-test3 but to a lesser extent means this is an intrinsic problem that needs a specific solution.
