What's the difference between the server1 code (shown above) and the server2 code (not shown, but identical as far as I can tell)?

What does the xvfb- run process do? What are the rest of the arguments? My guess is that, depending on the arguments, sometimes xvfb-run leaves files open even after the process terminates. You should monitor the open files with lsof which is available on most Linux systems. I don't know how to do that on other operating systems. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
