Refining classes in net/http

[forthrin]

What is the proper way to refine the initializer of this class? The below does not seem work.

require 'net/http'

module Foo
  refine Gem::Net::HTTPGenericRequest.singleton_class do
    def new(*)
      obj = super
      puts 'IT WORKS!
      obj
    end
  end
end

using Foo

http = Net::HTTP.new('localhost', '8080')
http.send_request('GET', '/')

@HoneyryderChuck: Do you have a solution here?
