Proper way to pass Queue to process when using multiprocessing.imap()?

When using pool.imap to apply a function over a list of values, what is the proper way to pass additional arguments to the function, specifically in my case a Queue that the process can use to communicate back to the main thread (for the purpose of reporting progress)? I have seen suggestions of using starmap, but this doesn?t appear to have a ?lazy? variant, which I have found to be very beneficial in my use case. The Queue is the same one for all processes, if that makes a difference.

I could just make the Queue global, but I have always been told not too. Perhaps this is an exception?
