A spike performance up, random delay in down might be sufficient mitigation on a multi-tenant platform.

On demand governor is already trigger happy enough to jump to maximum frequency with a slight increase in load, so one needs to add more delay in calming down step. A random hysteresis is bad from a system responsiveness aspect, because frequency scaling is not free (in terms of time) when observed from the CPU perspective.
