> See the "identical1" test case in DRILL-5266. Due to misconfiguration, the sort was given
too little memory to make progress. An OOM error occurred when allocating an SV2.
> In this scenario, the "converted" record batch is leaked.
> Normally, a converted batch is added to the list of in-memory batches, then released
on {{close()}}. But, in this case, the batch is only a local variable, and so leaks.
> The code must release this batch in this condition.
