This means once an ID is created, it will keep using the same PyObject instance. This has some advantages: - Avoids unnecessary re-creation of instances on UI poll / redraw. - Accessing free'd ID's gives an exception instead of crashing. (long standing annoyance!, though this only applies to ID's and not yet other data that uses the ID's - vertices for eg). - Allows using instance comparison (a little faster). Note that the instances won't be kept between undo.
