Neat separation of responsibilities between fork/process stuff and actual app 


  #!/usr/bin/ruby

  daemonize do
    worker = Resque::Worker.new(*queues)
    worker.work
  end

  def daemonize █
    child = fork
    if child.nil? # is child
      $stdout.close
      $stdout = open("/dev/null")
      $stdin.close
      trap('HUP', 'IGNORE')
      block.call
    else # is parent
      Process.detach child
    end
  end
