> as the `multiprocessing` module works just fine. Something that tripped me up when I last did `multiprocessing` was that communication between the processes requires marshaling all the data into a binary format to be unmarshaled on the other side; if you're dealing with 100s of MB of data or more, that can be quite some significant expense.
