Good point! You're right. Currently, there is one unstable pyc issue (except frozenset order which can be fixed by PYTHONHASHSEED). https://bugzilla.opensuse.org/show_bug.cgi?id=1049186 This is caused by interned string. Because of interning, reference count can be unstable. Like that, long objects, tuples and some others are cached and reused automatically. But they has refcnt>1 always: reference from object and cache. So we can use FLAG_REF always for interned string, even if refcnt==1. Let's try it and wait another issue are found.
