Nit; I would make stop_subscriber take a partition, and have it remove it from the map. Then we can never forget to keep the map in sync after calling this.

Nack. Then this function cannot be reused on teardown when looping over the active subscribers without making an explicit copy of the key set, otherwise you'll get a RuntimeError: dictionary changed size during iteration.
