This change makes mod_wsgi create standalone processes for horizon. This avoids obscure start up errors when mod_wsgi needs to spawn a new process or thread. These restarts occur, for example, when mod_wsgi receives a request from a client that is accessing the service through a non-standard SSL port that is mapped to the port mod_wsgi is listening on.
