> Ideally, classes like AbstractSingleRecordBatch() should call container.clear() to decrement
the reference count of the incoming ValueVectors before calling next() on the upstream operator.
 There is an issue with HyperBatches in this case though; the underlying ValueVectors should
not be freed implicitly.  That is, the operator should only clear the vectors when the entire
HyperBatch has been consumed.
> It has been suggested that a destroy() method be used to handle the HyperBatch case.
