You are trying to share state between two sandboxes (the iframe and the enclosing window) that are trying really hard to not let you share state!

I believe there are ugly ways to do this such as appending the parent's url with #<data> or using .swf

But the other solution is to use the shared state in freebase.  Assuming you know that the iframe has changed state (closed?) you could do a tiny MQL query to the graph to check the timestamp of the last link written by that user.
