hmm, I had not considered how creating a new partition affects the
material sorting. So I think what we want here is that the stage does
not create new partitions, but only takes control over traversing the
tree below it. Can you try removing the {begin,end}PartitionGroup and
{push,pop}Partition calls? That should cause the objects to be added to
the parent partition and thus sort normally with them.
Cheers,
Carsten
