internal error: looping module stopped

[Jacob Hoffman-Andrews]

I also got a number of these errors on an upgrade to Unbound 1.6.6, on a
server doing about 100-300 qps. Similar config: use-caps-for-id, IPv6,
DNSSEC. No non-default modules enabled. I also have a test harness where
I can reproduce these. What additional information would be useful?
