As far as I’ve gathered, race to idle has definitely been a focal point for Apple when it comes to power management along with coalescence of CPU and antenna wakeups — the system batches up work, powers up components, burns through the work as quickly as possible, and then returns components to idle/sleep. This is also why on iOS, apps that become known for abusing or mismanaging background processing are penalized and have their background processes run less often. Even just a couple of processes waffling around instead of completing their tasks and quitting can keep the system from idling and have a big negative impact.
