If I understand the GC plans correctly, it will use ref counting plus
an occasional cycle-detection pass (rather like Python itself).  This
approach won't does need to answer the question: "Given an object A,
what points to it?"  It only works in the other direction: "Given an
object A, what does it point to?"
