    should this be `shutdownNow`? My concern is that in some cases people set the akka timeout
to many seconds. If the driver has stopped its responding actor, this could hang for a long
time. Since this thread pool is only performing best-effort statuts updates, it seems like
doing a hard shutdown might be better.
