In case if application is under Apache+mod_wsgi it is not recommended to use signals [1]. We need to have configuration option for handling 'touch file' event instead of signal. Alternative solutions: 1) watchdog: can monitor only directories, has issues with eventlet [2]. 2) inotify: works only with linux-based systems.
