Partially elided patch to Resque to mitigate monkey patching need to support extra hooks

worker.rb

module Resque
  def self.hook_responders
    @hook_responders ||= [self]
    @hook_responders
  end

  def self.register_hook_responder(responder)
    hook_responsers << responder
  end 

  class Worker
    # Runs a named hook, passing along any arguments.
    def run_hook(name, *args)
      hook = Resque.hook_responders.find { |r| r.send(name) }
      return unless hook

      # ... 
    end 

  end 
end
