It is not clear that what you want to do can be done in the general sense. See Alex Martelli's explanation here: tackoverflow.com/questions/1268252/python-possible-to-share-in-memory-data-between-2-separate-processes/1269055#1269055 Any chance that instead of trying to share a PyDict you could share an array? If so, multiprocessing will work for you. Or the last reference there is to some lower level inter process communication things you can use in Python. I have never tried them, so have no idea how well written the code is. Laura -- https://mail.python.org/mailman/listinfo/python-list
