I haven't settled my mind yet about this.

If you want to preserve `initialize' behavior, here's the way:

  a) in `new':

        obj = Data_Wrap_Struct(klass, mark, free, 0);
        rb_obj_call_init(obj, argc, argv);

  b) in `initialize'

        ... you may destroy previous non null DATA_PTR(obj) ...
	DATA_PTR(obj) = allocated struct.
