I don't necessarily want threading in Node.js, but it would be nice to have coroutines/green threads...something simple that scales across CPUs, at least. Unfortunately with JavaScript I think the best you're going to get is Node's cluster module, because of the threading limitations with V8 and other JavaScript engines. Realistically, it's a trade off - Node.js is easy and quick to work with, but the only way to take full advantage of the machine's processing power is through forking processes.

Seriously, green threads with yield() and autoyield on blocking operations would be great. Sometimes the easiest way to write a program is to present it as a logical flow of events, and let the machine/operating environment hide the async nature of life from you.

Then again, that would mean reinventing (again) core OS functionality in Javascript. Le sigh.
