Thank you for testing the patches. 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!

Best regards,
// Ludwig
