I've ported over DBD::CSV's nice test suite (which was designed as a generic DBD test suite), and managed to get all relevant tests to pass. It's also about 10 to 30 times faster than DBD::CSV for inserts/updates/selects, though please test that for yourself before taking my word for it.

So download it, play with it, and let me know how you get on. It probably leaks memory here and there - I haven't done any tests on leaks yet. But overall it looks fairly stable. I haven't done *any* multiple server's connecting to it tests though - I'd certainly welcome testing in that area.
