W linku http://oldmoe.blogspot.com/2008/09/building-never-blocking-rails-making.html jest ciekawy artykul z testami z wykorzystaniem NeverBlock przy laczeniu sie z baza postgresql.
NeverBlock is a Ruby library that allows developers to write non-blocking, concurrent code in a transparent manner. Meaning that you will keep coding in your traditional ways while you get the benefit of non-blocking IO operations.
