The server fails with stdout=PIPE if I don't keep reading it, but doesn't fail if I do stdout=anything (I've tried files, strings, integers, and None) soon after starting the process, without any other changes. How is that consistent with either of the above conditions? I'm sure you're right, I just don't understand. Regards, John -- http://mail.python.org/mailman/listinfo/python-list
