When you are doing a locally-originated truly CPU-bound task, "race to idle"

1) If you care about power consumption, you want to avoid super-power-hungry

Thanks for the detailed response. I am heartened by the edge cases (true idle
and above up_threshold) remaining the same, that sounds like it should cover a
lot of ground well.

The "10" sounds like an attempt to add some hysteresis to the up/down
decisionmaking. If you take it out, you should make sure you don't get into
situations where you're continually switching rapidly between two frequencies.
