Yeah, that thought has crossed my mind. I did catch an addition error
in my logic that contributed to additional rollbacks. ;) But I did try
to be diligent and output everything that was going on in the
transaction to make sure there weren't any parallel transactions with
the same key. I feel confident that the logic is correct.
