Subject: Re: Circular References: How to prove that they are garbage collected


Oops... I put the end in the wrong place. It should be like this:

def main
   a = RingNode.new("Node A")
   b = RingNode.new("Node B")
   c = RingNode.new("Node C")
   a.next = b
   b.next = c
   c.next = a
   a.prev = c
   c.prev = b
   b.prev = a
   lonely = RingNode.new("Lonely node")

   a = nil
   b = nil
   c = nil
   lonely = nil
end

main
GC.start
...
