If I understand them correctly, fibers are like ruby threads (so they still don't bypass the Global Interpreter Lock) but they aren't automatically schedule, you can manually tell them when to continue and pause etc so you can make the most of the cpu time. Positive I don't completly understand whats going on but check out this presentation and associated blog posts.
