+           Discovered by John J and Robin J, the PowerDNS Recursor did not process packets that were truncated in mid-record, and also did not act
+           on the 'truncated' (TC) flag in that case. This broke a very small number of domains, most of them served by very old versions of the 
+           PowerDNS Authoritative Server. Fix in c1740.
