This is a further workaround: this time for the fact that we can't rely on tp_alloc, which zeroes the memory (including memory for subclasses, like slots in the test) for normal classes. For the test type, this means the instances aren't initialized twice (once in PyUnstable_Object_GC_NewWithExtraData, once again with PyObject_Init after zeroing). Initializing twice throws off the global refcount total in debug builds.
