> We have no visibility into whether reservations made by preemption are actually consumed
or simply expire.
> We are currently collecting stats for the size of preemption/reservation {{BiCache}}.
We could additionally collect (a) cache expiration stats and (b) reservation entry removals
in {{TaskSchedulerImpl.taskChanged()}} to monitor overall preemption effectiveness.
