If you don't want a connection to persist, don't add it to Application. 
Since a connection to an IRC server shouldn't persist (you may be connecting 
to other servers), it should be added to reactor directly. Since you 
apparently want *something* to persist, you probably want to add a 
twisted.internet.app.ApplicationService that will manage the connections.
