More than just a pretty web framework, the Tornado IOLoop

Tornado, often thought of as a web development framework and toolset is built on top of a protocol-agnostic IOLoop, presenting an alternative to Twisted as a foundation for asynchronous application development in Python. This talk covers the Tornado IOLoop, its features and the process of writing drivers and applications using it.
