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.


ps. please be nice to each other - both of you are long-time
scheduler contributors who did lots of cool stuff :-)
