+Subject: Move fd into frec_src, fixes 15b60ddf935a531269bb8c68198de012a4967156
+
+If identical queries from IPv4 and IPv6 sources are combined by the
+new code added in 15b60ddf935a531269bb8c68198de012a4967156 then replies
+can end up being sent via the wrong family of socket. The ->fd
+should be per query, not per-question.
+
+In bind-interfaces mode, this could also result in replies being sent
+via the wrong socket even when IPv4/IPV6 issues are not in play.
