This announces the "stop" event to our subclass. The "stop" event will occur when this DataLink is handling a release_reservations() call and determines that it has just released all of the remaining reservations on this DataLink. The "stop" event will also occur when the TransportImpl is being shutdown() - we call stop_i() from our transport_shutdown() method to handle this case.

writers_lock_ protects writers_, heartbeat_counts_ best_effort_heartbeat_count_, and interesting_readers_ along with anything else that fits the 'writers side activity' of the datalink
locators_lock_ protects locators_ (and therefore calls to get_addresses_i()) for both remote writers and remote readers
