I do not think that this is correct, the previous code compared the
return value from getpgid(0) against the rest, not parent pid.

I guess that the best solution here would be to call getgid() in the
parent and save that to a variable and use that for the comparsion in
the child.

I think I wrongly assumed the ppid to be pgid of itself and children processes.
Thanks for pointing it point.
