How to make rails wait

Hi,everyone.Here's my situation:
I have a controller like this:
class FooController < ApplicationController
  def delay
    sleep 10
    render :text=>"ok"
  end

        def normal
              render :text=>"ok"
        end
end

but I found that "sleep 10" will not only make the current request
delay 10 seconds,but also make the whole server sleep 10 seconds. That
means if I request "/foo/delay"and "/foo/normal" sequently on my
Browser,they both response after 10 seconds.But I only want the first
request delay 10 seconds while the others can normally work.
any Idea? thanks in advance

This is because mongrel and Webrick will only serve one request at a time.

Yes. And to be more specific: you have to use Mongrel cluster (do
'sudo gem install mongrel_cluster' and see http://www.google.com/search?q=mongrel_rails+howto)
for being able to serve more than one request simultaneously in
development.

Actually this is because *rails* can only serve one request at a time as it is single threaded. Other frameworks and apps that run on mongrel or webrick have no problems serving concurrent requests.
