    Create instances by calling tp_alloc rather than PyObject_NEW
    
    PyObject_NEW calls a generic allocator and should only be called by tp_new, knowing
    that the type's free function agrees. In pyg_boxed_new, we may allocate
    PyGBoxed subtypes, so the subtype's allocation function must be called instead.
