+ * A user-level addr query is translated into a number of protocol-level
+ * queries, and its job is to reassemble the results. This gets tricky if
+ * the answers aren't consistent. In particular, if the answers report
+ * inconsistent indirection via CNAME records (e.g., different CNAMEs, or
+ * some indirect via a CNAME, and some don't) then we have trouble.
+ *
+ * Once we've received an answer, even if it was NODATA, we set
+ * adns__qf_addr_answer on the parent query. This will let us detect a
+ * conflict between a no-CNAME-with-NODATA reply and a subsequent CNAME.
+ *
+ * If we detect a conflict of any kind, then at least one answer came back
+ * with a CNAME record, so we pick the first such answer (somewhat
+ * arbitrarily) as being the `right' canonical name, and set this in the
+ * parent query's answer->cname slot. We discard address records from the
+ * wrong name. And finally we cancel the outstanding child queries, and
+ * resubmit address queries for the address families we don't yet have, with
+ * adns__qf_addr_cname set so that we know that we're in the fixup state.
