And this also helps. Still trying to find out what clone/fork happens here.
As a new information, the problem only exists on Ubuntu,
I cannot reproduce it with Fedora or RHEL. I also changed
the kernel, its not the reason. As soon as I add tracing
the different timing also makes the problem go away.
