Yeah, I assumed the people 'in the know' on this kind of stuff would know
the details of why I have to have those, and therefore I wouldn't have to
go into detail as to why -- but you put your finger right on it. :)
Unfortunately the customer this is for wants certain columns joined at the
hip for querying and sorting, and this method was a performance godsend
when we implemented it (with a C .so library, not using SQL in our
opclasses or anything like that).
