Correction - BIND *does* do this, but only for address records that are 
already in the cache.   If the AAAA for the target is in the cache, but 
the A record isn't, that's all you'll get.

Mark's patch forces BIND to pre-fill the cache with the A and AAAA 
records for the SRV target before replying.
