 You can reduce the frequency that your configuration loader is called by
 wrapping it with `Resque::Pool::ConfigLoaders::Throttled` and specifying a time
-(in seconds) to cache the previous value (see [the
-spec](spec/config_loaders/throttled_spec.rb) for more details):
+(in seconds) to cache the previous value:
 
 ```ruby
 task "resque:pool:setup" do
   redis_loader = lambda do |env|
     worker_count = Redis.current.get("pool_workers_#{env}").to_i
-    {"queueA,queueB" => worker_count }
+    { "queueA,queueB" => worker_count }
   end
 
   # calls through to redis_loader at most once per 10 seconds
-  Resque::Pool.config_loader = Resque::Pool::ConfigLoaders::Throttled(

     redis_loader, period: 10
