python singleton into multiprocessing

Question

How can I code to share the same instance of a \"singletonic\" class among processes?

Answer 1

I do not think you can share the instance between the processes, but you can have the instance access shared memory: http://docs.python.org/library/multiprocessing.html#sharing-state-between-processes to control it's state if that is really what you want to do.

However, as stated in other answers, it might be easier to achieve what you want with a Queue.
