 There's one TODO item in the TSIG signing task: adding TSIG with
 truncated DNS message.  To do this we need to have the ability of
 knowing the length of expected TSIG RR (which also requires the
 ability of knowning the expected signature size), and if the message
 has to be truncated we need special processing of removing all
 inserted RRs and re-construct a message only containing the Question
 section and TSIG.
