I'm not convinced. It wouldn't surprise me if it was possible to generate endless cycles with rcu freed memory on some rebalancing operation. If you think I'm wrong please show working code. Also please explain clearly for the module maintainers and me what the problem with my original simple trivially show to be correct solution is.
