    Description

      Stepdown calls ReplicationCoordinatorExternalStateImpl::startProducerIfStopped, which takes _threadMutex while holding the global exclusive lock. Shutdown calls ReplicationCoordinatorExternalStateImpl::shutdown which takes _threadMutex and then does a database read by calling _storageInterface->getAppliedThrough.

      We should probably be doing the database reads/writes in ReplicationCoordinatorExternalStateImpl::shutdown after releasing _threadMutex.
