Review comment:
This is because the SlotProvider returns non-completed future. And eg is
configured as not allow queued scheduling. Thus when scheduleForExecutor, it
causes `IllegalArgumentException("The slot allocation future has not been
completed yet.")` and then failing and then restarting.
But it is tricky. Maybe I should set allow queued scheduling and fail a
future to emulate a real failure.
