Marshal.dump(Marshal.load(marshaled_hash)) is not guarenteed to be equal to marshaled_hash
because of the lack of ordering of hash

Examples:
  # Instead of render(:action => 'other_action')
  render('other_action')

Note : Argument must not have any '/'

Examples:
  # Instead of render(:template => 'controller/action')
  render('controller/action')

Note : Argument must not begin with a '/', but have at least one '/'

Examples:
  # Instead of render(:file => '/Users/lifo/home.html.erb')
  render('/Users/lifo/home.html.erb')

Note : Filename must begin with a forward slash ('/')
