No, the worker class is not defined as a Singleton. It's just that I  
need only one instance of the worker. I'm not using the worker for  
temporary background calculations (which seems to be the common use  
case), but instead as a background process that periodically updates  
the database and takes requests from the Rails app. It should not be  
killed and respawned because it has persistent connections to other
