Crude demo of async I/O using Celluloid::IO Actor with external class utilizing Celluoid::IO::TCPSocket. No need for GIL-less Ruby for this to work (except perhaps on the server, which isn't using evented IO for this demo)
require 'celluloid'
require 'celluloid/io'
class MySocket
def go
@sock ||= Celluloid::IO::TCPSocket.open('localhost', 2000)
puts "#{@sock.read}"
end
