The solution is to put the self.pool = Pool(process=4) as the last line of the daemonize method. Otherwise the pool ends up getting lost somewhere (perhaps in the forks). Then the pool can be access inside the run method which is overloaded by the application you wish to daemonize. However, the pool cannot be accessed in the stop method and to do so would lead to NoneType exceptions. I believe there is a more elegant solution but this works and it is all I have for now. If I want the stop to fail when the pool is still in action, I will have to add additional functionality to run and some form of message but I am not currently concerned with this.
