Wouldn't it be better if terminate() is just called as the first action if init() is called again? That way we would keep the previous behavior to just open again (and don't ignore e.g. another mode passed on to init()) and lose the old state (but this time without losing mem). Also I guess the same check+call of terminate() needs to happen in the dtor.
