has anyone used ANY object serialization library (other than pickle) with multiprocessing ? I just cant get anything else to work. We have a sophisticated desktop pyqt application that could really do with a better serialization with multiprocessing. I have heard of Pathos[1] to replace multiprocessing - but never gave it a try.
