Sure, but I agree I should be able to figure this out. Since
the database isn't designed to support my *business* logic needs
I obviously need to take proper precautions when following
business requirements.

I don't think I understand the difference well enough to
decide we can really go with the weaker isolation level. Hence
I decided to code for the stronger one.

That is, in fact, the most valid argument against what we are
doing now.

They need to write their own client.

There's a few other places where we aren't as portable as one
would wish.
