I understand that with Python, my choices are pretty much to either use Stackless (building from their Comet wsgi example) or Cometd + Twisted. Unfortunately there is very little documentation regarding these options and I cannot find good information online about production scale users of comet on Python. Has anyone successfully implemented comet on Python in a production system? How did you go about doing it and where can I find resources to implement

What are the modules used to write multi-threaded applications in Python? I'm aware of the basic concurrency mechanisms provided by the language and also of Stackless Python , but what are their respective strengths and weaknesses? quark In order of increasing complexity: Use the threading module Pros: It's really easy to run any function (any callable in fact) in its own thread. Sharing data is if not easy (locks are never easy :), at least simple. Cons: As mentioned by Juergen Python threads cannot actually concurrently access state in the interpreter (there's one big lock, the infamous
