I think that buffer is used when receiving a DNS message. The response
sending code uses a local buffer not one attached to the message object.
See client_allocsendbuf().

If you look at lines 1112 - 1118 you'll see the buffer containing the
rendered message passed to client_sendpkg(), and in the TCP case the
length of the response is inserted at the start.
