* Async - https://github.com/caolan/async - is very readable. Async is a great library for async ops handling in JS, and it's really neat seeing the implementation patterns.
* Ray - is a games DSL in Ruby - https://github.com/Mon-Ouie/ray - I love it, and it's a great read especially if you are interested in DSLs as much as I do.
* Jekyll - https://github.com/mojombo/jekyll - really helped me going forward with my ruby skills. It's nice, clean, commented, not too big, and useful.
* Redis - https://github.com/antirez/redis - lots of data structure implementations. Antirez just writes C so nicely. anet.c has networking, TCP bits, ae.c is an event loop. Lots of great code there.

Here's a few sources I really liked:
* Express - https://github.com/visionmedia/express - I don't like TJ's coding style, and general trolling of CoffeeScript, but this is a really great, clean and tiny codebase. (As well as all the connect middlewares - https://github.com/senchalabs/connect)

Let me add substack (https://github.com/substack) to your list. Lots of javascript/node gems.
