The ReplicaSetMonitor monitors membership changes of all the known replica set shards in mongos and tries to update the ShardRegistry and config.shards. The issue is that when the ShardRegistry::reload gets called, it will clear all it's entries and tries to reread the contents from config.shards. So there is a small window were the ShardRegistry 'forgets' the newly added replSet member until config.shards get updated and reload gets called again.
