Eventmachine talk - Jan 2008 - EM beginner example code snippet

Hi Devs,
Before I post a code snippet I should get it working :)
In the following I don''t see the client quit/stop.  I''d
appreciate any
suggestions.
Here it is.

== Examples
=== Robotic echo client and server
Here''s a fully-functional (and automatic) echo server and its client
written with
EventMachine - in two steps

1) Start an instance of irb in a new shell/dos command prompt
  #### Start server code ####
  $stderr.sync = $stdout.sync = true
  require ''rubygems''
  require ''eventmachine''

   module EchoServer
    def receive_data data
      puts "Server received:  #{data}"
      send_data ">>>you sent: #{data}"
      puts "Server sent:  >>>you sent: #{data}"
      (puts "CLOSING"; send_data "quit";
close_connection(true);
EM.stop) if data =~ /quit/i
    end
   end

  EM::run{
    EM::start_server "127.0.0.1", 8100, EchoServer
  }
  #### End server code ####

2) Start another instance of irb in a new shell/dos command prompt
  #### Start client code ####
  $stderr.sync = $stdout.sync = true
  require ''rubygems''
  require ''eventmachine''

   class EchoClient < EM::Connection
    def receive_data data
      puts "Client Received: #{data}"
      (puts "CLOSING"; close_connection(false); EM.stop) if data =~
/quit/i
    end
  end
   cnt=0
   EM::run {
    emc = EM::connect "127.0.0.1", 8100, EchoClient
    EM.add_periodic_timer(5) do
      cnt +=1;
      if cnt <= 3
        emc.send_data "Message: #{cnt}"
      else
        emc.send_data "quit"
      end
    end
   }
  #### End client code ####
In the server shell/command window you should see:
  Server received:  Message: 1
  Server sent:  >>>you sent: Message: 1
  Server received:  Message: 2
  Server sent:  >>>you sent: Message: 2
  Server received:  Message: 3
  Server sent:  >>>you sent: Message: 3
  Server received:  quit
  Server sent:  >>>you sent: quit
  CLOSING
  => nil

In the client shell/command window you should see:
  Client Received: >>>you sent: Message: 1
  Client Received: >>>you sent: Message: 2
  Client Received: >>>you sent: Message: 3
