  #   code that you don't normally modify during development in the
  #   Spork.prefork block.
  # - Place the rest under Spork.each_run block
  # - Any code that is left outside of the blocks will be ran during preforking
  #   and during each_run!
  # - These instructions should self-destruct in 10 seconds.  If they don't,
  #   feel free to delete them.
