Created May 1, 2011 01:23 — forked from pietern/redis_pubsub_demo.rb

	# Author: Pieter Noordhuis
	# Description: Simple demo to showcase Redis PubSub with EventMachine
	#
	# Update 7 Oct 2010:
	# - This example does not appear to work with Chrome >=6.0. Apparently,
	# the WebSocket protocol implementation in the cramp gem does not work
	# well with Chrome's (newer) WebSocket implementation.
	#
	# Requirements:
	# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

Manage ActiveRecord connection pool with rack handler

	#This is a Rack middle to release the connections checkout from the connection pool
	#in a rack multithreaded environment
	# This is mandatory outside of ActionController, as ActiveRecord request you to handle the
	# release of the connections into the pool. If you don't do it, every n thread (where n is
	# the AR connection pool size) will be stucked waiting for a 5s AR empty pool timeout
