Review Comment:
   That's what I thought before, but in the case of `multiTopicConsumer` it 
causes the chan to be closed repeatedly.

   This is because although the consumers are multiple instances, they use the 
same `messageCh` and can only be closed once.
   
   So I'd like to record the closed flag for `messageCh` via a global variable.
   
   
   With regard to the `closeChanSet` leak, we can set it to `nil` in the 
`client.Close()` method.

   Is there a better way?
