> PORelationToExprProject currently uses "BagFactory.newDefaultBag()" to create an empty
bag in cases where it has to send an empty bag on EOP - each such empty bag created will be
registered with the SpillableMemoryManager as a spillable bag. Since it is an empty bag, it
really should not be registered as a spillable bag. For this, NonSpillableDataBag can be used.
