Multi-threading is important in many applications, from primitive servers to today's complex and hardware-demanding games, so, naturally, many programming languages sport the ability to deal with threads. This includes Python. However, Python's support for multi-threading is not without limitations and consequences, as Guido van Rossum writes: "Unfortunately, for most mortals, thread programming is just Too Hard to get right....

Have a lot of files to process, but don't know how to distribute NLTK across many cores? Well, here's how you can use execnet to do distributed part of speech tagging with NLTK.
