I'll not be excited about any attempts to make our already-a-database
backend more of a hybrid-of-multiple-databases backend. The shared code
benefit simply doesn't outweigh the mental hoop jumping required to
understand why some data is stored in one database and the rest in another.
Besides, all the nice atomicity guarantees of BDB break down when you've
got to interact with a non-BDB data store, too. If it's not obvious, I'm
already bummed that we're using sqlite in the BDB backend, but I think it's
too late to try to remedy that at this point.
