> The pin logic is for adding the reference counter based on number of
> subpartitions for {{ReleaseOnConsumptionResultPartition}}.
> It seems not necessary to do it in while loop as now, because the atomic
> counter would not be accessed by other threads during pin. If the
> {{ReleaseOnConsumptionResultPartition}} was not created yet, the
> {{createSubpartitionView}} would not be called actually resulting in
> {{PartitionNotFoundException}}.
> So we could simple increase the reference counter in
> ReleaseOnConsumptionResultPartition constructor directly.
