As we lost exit code without this patch, test case is highly impacted, I will merge this.

@marc-hb yes, it looks have some gap with original design, you also can submit the PR to fix it :)

I don't submit without testing, what is the easiest way to test this particular code locally? I see @plbossart filed a number of usability issues.
