Feature: Rails Delayed Work arounds
  To allow a rails developer to update as many parts of his application as possible without needing to restart Spork
  Spork automatically tells rails to delay loading certain parts of the application until after the fork occurs
  Providing work arounds

  Background: Rails App with RSpec and Spork
