Thanks again, the recipe was very useful, and in the meantime I also
found this article,
http://www.informit.com/content/images/art_deitel_creatingprocesses/elementLinks/pythonhtp1_fork_article.pdf
which explains os.fork and os.wait in a python context. Maybe some
others will also make use of it, it clearified the basics for me.
