Because I have two tables, A and B, both of which I need to bulk load.
B has a foreign key to A. A has constraints on it. B has no
constraints.
So I have two files, one for loading A and one for loading B.

If I bulk load A and some of the constraints kick out records, such
that not all of the records load, then when I load B, I will not have
a way to know how to set the foreign key in B correctly.

If I was just loading one table, your point would be totally valid.

Thanks,
Wes
