> Affects Versions: 0.13.0

>
> When processing multiple splits on the same operator pipeline, the output
> collector in Operator has a held reference, which causes issues.
> Operator::close() does not de-reference the OutputCollector object
> Operator::out held by the object.
> This means that trying to allocate space for a new OutputCollector causes an
> OOM because the old one is still reachable.
