That idea definitely needs some refinement.

Run test-starve.c, and try to login. I'm not sure, but I don't think I've
seen any task change more than one priority from what it started life
at. In test-starve's case, that's 16. It's partner is at 16 as well, so
it can't preempt (bad). A dd if=/dev/zero of=/dev/null stays glued to
21. Repeated sh -c 'ps l $$' bounces back and forth between 15 and
21. (maybe I should fly to Vegas.. when I try to login with test-starve
running, I keep hitting 21:)
