8.2.2-P5 caches the response, overwriting the cached servers already
there.  Interestingly, 8.2.2-P3 logs the following:
    Sep  6 08:02:20 zz named[5365]: bad referral (com !< EROSROUGE.com)
So this would seem to have become broken between 8.2.2-P3 and 8.2.2-P5.

8.2.3-t7b still has the defect.

Not blocked...  sigh.  Looks like a shipstopper to me...

Off to make some diffs.
