Is there any particular reason you're using processes and not threads?
Functions that wait for stuff to happen in C land, such as I/O calls,
release the GIL so threads can be run in parallel. It's only stuff
that happens in Python land (i.e. manipulating Python objects) that
can't be run concurrently.
