Hi @kanzhang, we have a long-running discussion about this at #251. Joining
on the thread is a simple alternative to what is proposed in the other PR, but
at the same time preserves clear semantics (i.e. all events before STOP will be
processed to completion, and no events after STOP will be processed). Both
@pwendell and I are inclined towards this approach.
Could you add a test for this? #251 provided an excellent example of this.
@concretevitamin could we use your test case here? We'll be sure to credit both
of you.
