Python has good support for multiple threads running on a single 
processor. The GIL prevents Python from effectively running multiple 
threads on multiple processors.

You might also be interested in Twisted which provides 
industrial-strength servers using an asynchronous model rather than 
threading. There is an example of a simple UDP echo server here:
