Thanks for your input.
1) You are right, "Yes" and "No" is the more straight way for this question.
2) Thanks to this hint, now I understand finally that these methods like do_start from getnew.py (and other files as well) override the method stubs provided by subprocess.py. This shows one more time how useful a developer documentation would be. ;)
3) Ok, here I confused None with the empty list, fixed.
