- ares__send_query() now varies the retry timeout pseudo-randomly to avoid

  packet storms when several queries were started at the same time.

* January 11 2009 (Daniel Stenberg)

- Phil Blundell added the internal function ares__expand_name_for_response()

  that is now used by the ares_parse_*_reply() functions instead of the

  ares_expand_name() simply to easier return ARES_EBADRESP for the cases where

{

  struct send_request *sendreq;

  struct server_state *server;

  int timeplus;

  server = &channel->servers[query->server];

  if (query->using_tcp)

          return;

        }

    }

    timeplus = channel->timeout << (query->try / channel->nservers);

    timeplus = (timeplus * (9 + (rand () & 7))) / 16;

    query->timeout = *now;

    ares__timeadd(&query->timeout,

                  channel->timeout << (query->try / channel->nservers));

                  timeplus);

    /* Keep track of queries bucketed by timeout, so we can process

     * timeout events quickly.
