Clojure core.async
summary
A Clojure library implements CSP-style channels so independent logical threads communicate via queue-like endpoints rather than tangled callbacks, with a go macro that turns blocking operations into parked continuations so JVM threads or a shared thread pool can be used and the same API runs in ClojureScript. It provides alts/select for waiting on multiple operations, timeout channels as first-class timers, fixed or dropping/sliding buffers (no unbounded buffers), async put/take bridges for callback interop, and it works as advertised.
