​Wait... you're suggesting swapping the listener inside of the
IceTransport?  Hmmm... that would be an interesting approach that I hadn't
considered.  I guess that would be "option D".

​If you called IceTransport.restart()​ on an IceTransport that came from
IceListener, that would "detach" itself from the Listener.  Why would you
want to stay attached to the IceListener?
