That's basically my opinion. It's unlikely to get more broken than it
already is. I've already found several unrelated bugs while studying
the code :-(. For starters, it doesn't come close to working correctly
when there's more than one overflow-page-bitmap page. Since we've not
heard reports of problems, I doubt anyone's exercised it with large
numbers of overflow pages.
