This is the first real episode in the Clojure Concurrency series. It covers a lot of material: vars, atoms, refs, agents, futures, promises, delays, unified succession model, deref with timeout and a brief mention of other concurrency options. Lots of the topics will be covered in more detail in a separate episode.
