> ArrowEvalPythonExec.doExecute and the non-codegen
> ColumnarToRowEvaluatorFactory flatten columnar batches into rows without
> calling closeIfFreeable (SPARK-50235), so a source that allocates new vectors
> for every batch and relies on its consumer to release them keeps them until
> the end of the task. As suggested in the review of
> https://github.com/apache/spark/pull/59551.
