Comment (by jinmei):

 I created a ticket I intended (#2239).  And my suggested revised
 comment to `SyncUDPServer::handleRead` is as follows:

 {{{#!cpp
     // Make sure the buffers are fresh.  Note that we don't touch query_
     // because it's supposed to be cleared in lookup_callback_.  We should
     // eventually even remove this member variable (and remove it from
     // the lookup_callback_ interface, but until then, any callback
     // implementation should be careful that it's the responsibility of
     // the callback implementation.  See also #2239).
     output_buffer_->clear();
     answer_->clear(isc::dns::Message::RENDER);
 }}}

 If the ticket and the comment make sense to you, please merge the
 branch with the added comment.
