I tested without use-caps-for-id, and did not get the "looping module
stopped" error.

I also upgraded to 1.6.7 and applied your patch. Here is a sample of
some of the queries and log messages I got. I was loading Unbound with a
mixture of A and CAA queries pulled from the logs of all names in
certificates issued by Let's Encrypt.

Also worth noting: I set up this test harness in order to reproduce an
issue with harden-referral-path where all queries time out after a
certain amount of time. However, I suspect the "looping module stopped"
issue is separate because I get that message even in test runs with
harden-referral-path disabled. I'll file an issue with details about the
timeout problem soon.
