Default workload behaves as expected now, but specifying something
different here via -W let the script hang on the workload startup.

Basically, it runs fine. But I have two further suggestions:

o some kind of summary of the completed rt-tests on script termination.
  I know what to lock for in the logs, but will the newbie do so?

o a switch to control the test periods. I'm playing with a patch to
  control the aperiodic timer resolution. When I tune it to 1 ms e.g.,
  having an option to push the test tool periods at this level as well
  would be nice.

Thanks a lot for your effort!
