You could create a named pipe in /tmp with a unique (static) name and permissions that disallow any kind of read/write access. Then simply have your script check for its existence when it starts. If it exists, then another instance of your script is running, and just terminate. Make sure your original instance removes the pipe when it exits. -- http://mail.python.org/mailman/listinfo/python-list
