Well, if you drop an eye to what Peter is trying to point out, you'll
find a lot of examples where providing an RT application with _more_ CPU
than it asks, lead to catastrophic consequences... They are some of what
we call "scheduling anomalies", and there are plenty of examples of
that! :-O

I think sched_rt determinism could be improved... But giving some random
task some random more bandwidth is just going in the opposite
direction! :-(
