Appreciate it! The test program from Michael was of great help when I analyzed the root cause. Thanks for sharing it on the list. I'll send a new version of the series (this patch will however remain unchanged, so I'll pick up your test tag). If you have the possibility to re-run the clone3-tests on it would be great. Thanks!
