> Currently when a query has a limit with no order by, we run it serially. When
> there's a selective query, performance will be bad. Instead we should run it
> in parallel, pushing the same filter we currently do for the scan that runs
> serially to limit the output for each region. Then, on the client, we can put
> a LimitingResultIterator as the last iterator so that we only see N results
> max.
