I disagree that refcounting == GC.  The point of GC is that you
*don't* know how many references to a given object exist until you
manually check.  In a sufficiently vague sense you could say that
refcounting is a form of GC, but I don't see that as being very
useful.

I seriously doubt this is a flaw of refcounting.  It is most likely
an artifact of your implementation.
