You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: timeout.rb
    path of file: ./repos/jruby/spec/mspec/lib/mspec/runner/actions
    
    the code of the file until where you have to start completion: class Timeou
    
  def start
    @thread = Thread.new do
      loop do
        if action = fetch_item
          action.call
        else
          wakeup_at = @started + @timeout
          left = wakeup_at - now
          sleep left if left > 0
          Thread.pass # Let the main thread run

          if @queue.empty?
            elapsed = now - @started
            if elapsed > @timeout
              if @current_state
                STDERR.puts "\nExample #{@error_message}:"
                STDERR.puts "#{@current_state.description}"
              else
                STDERR.puts "\nSome code outside an example #{@error_message}"
              end
              STDERR.flush

              show_backtraces
              if MSpec.subprocesses.empty?
                exit! 2
              else
                # Do not exit but signal the subprocess so we can get their output
                MSpec.subprocesses.each do |pid|
                  kill_wait_one_second :SIGTERM, pid
                  hard_kill :SIGKILL, pid
                end
                @fail = true
                @current_state = nil
                break # stop this thread, will fail in #after
              end
            end
