When I add autoreload functionality to my programs I just spawn a thread that checks for last modified date and then re-executes the program with os.execlp(sys.argv[0], *sys.argv) I found my solution superior in several ways: - I can force an autoreload just by saving a file (no file changes needed to force an md5 diff) - exec() doesn't suffer from the side effects of not restarting the python interpreter, clean start every time :) - it is also quite portable and doesn't require extra dependencies like inotify/fswatch/etc. </ul>
