Lack of convinction that we'd chosen the correct defaults is the reason
we made them configurable. You can adjust max-recursion-queries if you want

However, in this case I think it's because you had an empty cache, and
sending a second query will clear the problem up.  In a future release, we
may want to lift the restrictions temporarily while priming.
