So, from what I can tell, Pluton : C/State-Threads :: Twisted : Python/select. It's a hybrid evented/threaded framework using cooperative thread scheduling, but it hides the thread scheduling in its API to make programming feel even more natural.<p>There are a lot of random projects that chased this idea; maybe someone here can list a couple? I'm just fascinated that Yahoo fielded major apps built on this one. Neat!
Very cool, glad that got out, it's good to see stuff like this happening. Its been in use for 5+ years so hopefully others can find use for it as well.
