Thanks for adding the test. It looks good, just a few more comments.

PS3, Line 52:   handle = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            :   handle.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
            :   handle.bind(('localhost', 0))
            :   _, port = handle.getsockname()
Does this mean that every "statestore subscriber" uses the same port? Looks 
like this would run just once at class initialization?
