Review comment:
Semantics of this have changed, but I'm not seeing conversation that
indicates that it was intentional.
Before: we would stop all workers, then wait for them all to be stopped.
Each worker could stop itself concurrently. Now, for each worker, we request a
stop and then wait for it to be stopped, then move on to the next worker.
I don't _think_ this is a big deal, but wanted to call it out.
