Comment (by jinmei):

 I've merged the quick hack fix in master.

 Replying to some other comments:

 > One note, if the receiver sends a response being either success or fail,
 shouldn't the sender be interested in this?

 In general, it should, I think.  Especially in the case of fail, the
 sender
 may have to take some recovery action.

 > Anyhow, I say add receives to the sender now for a quick solution, and
 for a more permanent solution, I propose we add a field to the command
 specification that specifies whether there will be responses to control
 commands. If that is true, senders MUST recv() at some point after
 sending, and receiver MUST respond(). If false, both MUST NOT.

 That looks like making sense.

 I'm going to close this ticket for now, and open a new one as a backlog
 for more complete tests and cleaner solution.
