Well, the way you posed the original question: > from subprocess import Popen > popen = Popen(["ping", "google.com"]) > from time import sleep > sleep(100) is really what adoption by init is designed to handle. Here you've created a child but have not waited for its return value. Like a good adoptive parent, init will wait(2) for the child. I think if you really looked into it you'd find that the terminal had called wait(2) before it was killed. Similarly, if you start a long- running subprocess in python and wait for it to return -- killing the parent will slaughter the child as well. hth, Michael --- Let the wookie win. -- http://mail.python.org/mailman/listinfo/python-list
