var env map[string]string
if err := json.Unmarshal([]byte(args), &env); err != nil {
env = []string{args}
}
if err := b.commit("", env, fm.Sprintf("ENV %v", env)); err != nil {

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
end

Poll returns immediately after the page is loaded for some reason... any ideas?
@Poller =
delay: (ms, func) -> setTimeout func, ms
poll: (url,time)->
@schedulePoll(url, time)
$.getScript(url)
schedulePoll: (url, time=30000) ->
poller = @delay(time, =>@poll(url, time))
$(document).on 'page:fetch', =>
clearTimeout(poller)
