When you set "Do not use recursion" on a forwarder, it means that DNS will
wait until the query times out for an answer from the forwarder, if the
forwarder doesn't answer, the query fails and it won't use recursion from
the root servers. This is handy when you need to resolve a trusted domain,
and it would be unacceptable for it to query the Root Servers for a private
domain.
