Re: [PATCH rt-tests v3 27/33] pip_stress: Return failure code if test fails

It isn't really an error if no priority inheritance occurs.
An error from this program would be something like mmap returning an error 
code.

I'm not sure this one is suitable for the json treatment, it's more of a 
demonstration of how to use priority inheritance with processes instead of 
threads. Thomas told me this was possible and I was curious to see if this 
was true, so I scratched that itch. Not sure if it is useful as a test.

Let's leave pip_stress alone for now please

If it's a for demonstration purposes only, could we remove it from the
source tree? I don't think it should be left there if it's not
considered a proper test.
