Yes, that's exactly the kind of thing that makes many CPython users consider
RC to be "a feature".  There's no reason at all to believe that CPython will
ever give this up; even NeilS's BDW patch for CPython retains refcounting,
simply for *speed* reasons (RC has excellent locality of reference,
especially when trash is being created and recycled at high dynamic rates).
