  monkey patching works again. See discussion at https://github.com/defunkt/resque/pull/895 for more
  context (@jonhyman)

  https://github.com/resque/resque/pull/902 (@jonhyman)

  method causing job failures to no be reported, #792 (@sideshowcoder)

  would crash workers.

  certain failure backends (@kjg)
* Web UI: Add page list to queues (@ql)

  multiple hooks using an array, #859 (@jonhyman)
