Cycles are one of the reasons for using Free or other explicit 
finalizers, regardless of the GC model.

Mark-sweep collectors can remove also clusters with cyclic references, 
but they can/should not call the destructors of these (any) objects, 
because this could result in infinite recursion or other unwanted 
effects. Clearing the references before calling the destructors is not a 
solution, because it can prevent proper operation of the destructors.
