I'm not sure about that discussion, but there's good evidence from
C++ that refcounting with atomics works. What was the smoking gun?

 I don't see how that link answers Andrei's question? He just compares
different methods of implementing COW.

As I understand the issue it works if you make sure to transfer
ownership explicitly before the other thread gains access?

Maybe this is more clear:

This describes the scenario I meant in the ARC discussions.

Thanks for the link, I didn't know a solution exists. I'll have to study 
the "differential" approach to see if it works for our case and at what 
cost it comes...
