I believe this should have happened before we applied a series of
fixes to the UDP server class.

As explained in http://bind10.isc.org/ticket/2942#comment:18 the
fundamental background issue is that there's a mixture of query
handling and other general CC communications.  For a middle term I
guess #2861 can work as a workaround if we implement the deferred
listening suggested in the ticket.  For a longer term, I believe we
should make these CC communications completely asynchronous and stop
running the ASIO loop internally.
