> In some situations, we may want to forward stop requests to external runtimes, e.g. gRPC (see https://github.com/apache/arrow/pull/10318 ), without polling.
> Ideally, one may temporarily add a callback to a StopToken. This bears complications, especially in the case where the stop request comes from a signal handler.
