The Python 2.7 multiprocessing module API is ~5 years old at this point, Andrew's referring to the API in Python 3.4+: https://docs.python.org/2/library/multiprocessing.html#module-multiprocessin...
As far as the other benefits of asyncio go, one of the perks is that you can stop all processing smoothly just by stopping the event loop, and then they'll all resume together later. This gives you a lot more predictability than using threads or processes, which genuinely execute in parallel.
After the previous discussion, I wrote http://www.curiousefficiency.org/posts/2015/07/asyncio-tcp-echo-server.html to attempt to convey some of the practical benefits of using asyncio to manage interleaved network operations within a single thread. While in the blog post I'm just playing with TCP clients and echo servers at the interactive prompt, it wouldn't be too hard to adapt those techniques to running network client and server testing code as part of a synchronous test suite.
