Wow, that sounds pretty cool.

You say I did that? :)

I'll take a look, but I'm not sure if I still have that. This sounds familiar, but I can't remember it at the moment.

In the meantime, take a couple of hours and walk through the developers code. My experience is that they either can't or won't do a 'desk check' and don't really know what is going on in their own code.

They also often commit too frequently or not often enough, or do a commit while a update cursor is open and wonder why they get a fetch across commit error on the next fetch.
