An alternative way is just call PyType_Ready from _PyType_Lookup if type->tp_mro is NULL.

Here is a patch against 2.7 that restores the solution from issue551412, but returns NULL if type->tp_mro is still NULL after calling PyType_Ready. I found one place in tests when this is happened (CIOTest.test_IOBase_finalize in test_io).
