i have to agree with Mike that this is a material regression that cannot be talked around.
Con, we want RSDL to /improve/ interactivity. Having new scheduler interactivity logic that behaves /worse/ in the presence of CPU hogs, which CPU hogs are even reniced to +5, than the current interactivity code, is i think a non-starter. Could you try to fix this, please? Good interactivity in the presence of CPU hogs (be them default nice level or nice +5) is _the_ most important scheduler interactivity metric. Anything else is really secondary.
