Example using NewRelic with after_fork for Unicorn but always doing so even for Resque workers

Rakefile

require 'rubygems'
require 'bundler/setup'

class SomeJob
  @queue = :some_queue

  def self.perform
    puts 'working - actually, sleeping...'
    sleep 1
    puts 'done'
  end
end

Bundler.require :default
NewRelic::Agent.after_fork(:force_reconnect => true) if defined?(Unicorn) && defined?(NewRelic)

require 'resque/tasks'

task :default do
  Resque.enqueue SomeJob
end
