The push task is a separate task from the recv task, so its state needs to be tracked separately for waking. I don't know how to be systematic about ensuring that notify_push is called in all the right places, but this is an initial attempt.
In order to test this works, we manually utilize FuturesUnordered which does fine-grained task wake tracking. The added test failed before making the other changes.
