Review Comment:
@westonpace, the approach here is from an offline discussion with you that
was active just a few days ago, and in my experiments `StopProducing` wasn't
enough. What progress with `StopProducing` are you referring to? What is the
approach you are currently in favor of? If it ends up being straightforward,
then I'd be in favor too, but I'd like to first validate this is the case.
