We should only output to the user once. We're ignoring most of the output
because we're not actually fetching anything real here, all the hashes are
bogus, so it's just going to be errors and a final summary of all the misses.

fetch warning!
We should output to blackbox three times, with a stack trace on each (though
that isn't tested here).
