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.
