docs: /*
  Start a new thread that using the LinkedBlockingQueue, every time there is a new element in the collection
  will retrieve the last updated users HashMap and calls container and will use them to produce and dispatch a new repsonse
  to the clients in the queue.
  Important here is the fact that we never close the stream and we just flush the response so it can be used later when needed.
