 During handling of the above exception, another exception occurred:

 Verbose mode gave me more information:

 {{{

   File "/home/reed/opt/bind10/libexec/bind10-devel/b10-msgq", line 156, in
 setup_listener
     self.listen_socket.bind(self.socket_file)
 socket.error: [Errno 13] Permission denied

 }}}

 But didn't give me the path.

 msgq should give a clear error message that says the path without the
 python noise.

 bind10 should also not have any traceback. It should say that the msgq
 exited.

 And why SIGKILL? (versus friendlier signal)

 (I know the problem with msgq, but that is unrelated to this ticket.)
