The Celluloid Ecosystem
summary
Celluloid is a concurrent-object framework for Ruby that offers synchronous calls, async do syntax and Futures, automatic pools (one actor per CPU by default), and built-in supervisors for fault tolerance; pools scale to cores and supervisors restart crashed actors. The ecosystem includes DCell/Diesel (distributed via ZeroMQ and ffi-rzmq), which currently ships as a pre-release and requires Zookeeper for node registry while linking is not yet implemented, Celluloid::IO for evented sockets, and Reel, a WebSocket-capable server that demos a time-push and beats Goliath on latency though Thin and Node remain faster.
