Hmyes, tricky. This would hurt performance quite a lot as any recursive
question for which no answer is available leads to a potentially very large
number of SQL queries.

I added a feature for this in 2.9.14:
  arg().setSwitch("recursion-check-nxdomain","Set this to double check if
recursive queries really don't exist")="";

Can you try this for me when I releas 2.9.14 later today?
