       That sounds reasonable. In this case, Instead of creating a
helper as Turpish suggested, I propose to create another method to
create a process assuming argv[0] = process name. This way, if using
it when needed, may provide a more readable code by decreasing the
redundancy in the code.

       Also, thanks for the info. I didn't research the matter yet,
but maybe the argv[0] can help with the problem to identify and send
signals to other processes in both platforms.
