that stuff i knew.  but people think it buys them something, so they
continue to use it.

i'll buy that.  but the server in question is running 8.2.  8.2 (i've
verified) does it wrong by returning all the CNAMEs and then one A
record.  8.2.1 on the other hand, seems not to return varying CNAME/A
answers, even if the zone has multiple cnames and the server is told
to allow it.  i even tried turning on "rrset-order { order cyclic; };"
but it didn't "help".
