Without this we free the entire `TopNOperator` and then pitch the reference to it. It'd be best if these two things were atomically locked together, but so long as everything we free is small-ish we can live with keeping the reference for a bit. We reserve some room to maneuver here. But if the thing we're freeing is quite large this ain't great. We think we have room to allocate but we don't. With this we pitch the reference to each row as we go so they can be GCed immediately. This keeps the untracked-but-hard-referenced state to a single row at a time.
