Subject: Simple Server Question

Guys -

I'm working on a simple Chat Server/Client just to become familiar with
ruby socket programming. I've put together this very simple server that
accepts a connect and prints out the first message received. I've done
this in Java as well, but the issue I'm finding here is I cannot ctrl+c
to quit the server. Do I need to create a thread to listen for keyboard
input and then pass this to a quit method? It seems to me that ctrl+c
(or ctrl+z depending on os) should always force quite a running program,
right? In this case, it's just hanging. Any help appreciated.

require 'socket'

class ChatServer

  def initialize(port)
    @port = port
  end

  def run_server

    @sessions = {}
    @my_server = TCPServer.new('localhost',@port)

    puts "Server running...."

    while(session = @my_server.accept)
      @action = session.gets
      puts @action
    end

    @my_server.close
  end

end

my_server = ChatServer.new((ARGV[0] || 80).to_i)
my_server.run_server
