For the current code right now, any thread who calls getMaster (and also the ReplicaSetMonitorWatcher) can potentially change the _nodes vector. It is easy for multiple threads to do duplicate work since it is relatively easy for a thread to be replaced by another because it will be blocked when it calls isMaster.
