So the problem is that readinto(view) might result in several references to view? I don't think that can be solved on the memoryview side. One could do: view = PyMemoryView_FromObject(b); // Lie about writability ((PyMemoryViewObject *)view)->view.readonly = 0; [...] Then the view owns a reference to the bytes object. But that does not solve the problem that writable memoryviews based on a readonly object might be hanging around.
