faraday and em-synchrony

em-faraday.rb

#!/usr/bin/env ruby
require 'faraday'
require 'em-synchrony'
require 'em-synchrony/em-http'
require 'em-synchrony/fiber_iterator'

conn = Faraday::Connection.new(:url => 'http://localhost:5000') do |builder|
  builder.use Faraday::Adapter::EMSynchrony # make http request with eventmachine and synchrony
end

EM.synchrony do
  queries = 1..5
  results = []

  conn.in_parallel do
    #EventMachine::Synchrony::FiberIterator.new(queries, 5).each do |query|
    queries.each do |query|
      resp = conn.get do |req|
        req.url "/search?q=foo+#{query}"
      end
      results.push resp
    end
  end

  results.each do |r|
    p r.body
  end

  EM.stop
end

I would like to ask if you can guide me to solve, thank you in advance.
