I agree that refcounting solve this, as I mentioned it in
previous mails, but don't agree that it is the correct
solution in a case where the two resources have a
hierarchical links and which is solvable without refcount.
Refcounting comes with its own flaws and is far harder to
implement in the current state for the reasons your mention
