Subject: streaming with webrick

Can someone explain to me why the following serverlet doesn't stream
Hellos.

require 'webrick'

class Streamlet < WEBrick::HTTPServlet::AbstractServlet
  def do_GET(req, res)
    res["content-type"] = "text/plain"
    r, w = IO.pipe
    res.body = r
    res.chunked = true

    Thread.new do
      5.times do |i|
        w.write("hello #{i}\n")
        sleep(1)
      end
      w.close
    end
  end
end

@server = WEBrick::HTTPServer.new(:Port => 4711)
@server.mount("/stream", Streamlet)

trap("INT") { @server.shutdown }
@server.start

Thank you.
