Last I heard, the Persistent base class, written in C, uses old tricks that are kind of deprecated; if I remember correctly, before Python 2.2, it was known as the place that introduced the trick called "extension classes" to Python, which later became "new-style classes" in Python 2.2. So I would not be surprized if that causes the user-visible __dict__ of its instances to miss an attribute like "_container" or "data", and so be generally unsupported by PyPy's cpyext. If you really care about it, you may want to rewrite at least the base class, persistent.Persistent, in pure Python. A bientôt, Armin.
