When the prompt thread is started, it will wait for an item to be placed in the request_queue using the request_queue.get() method. If there is nothing in the request_queue, the thread will block and wait until an item becomes available.

In other words, the prompt thread will be idle until it receives an item in the request_queue. Once it gets an item from the queue, it will process the content and execute the remaining part of the function. If you want the thread to exit gracefully when there's nothing in the queue, you can consider using the get() method with a timeout, like request_queue.get(timeout=5) to wait for a certain amount of time before giving up.

정답은 request_queue가 올 때까지 기다린다입니다. 따라서, 만약 오류 발생 시 메모리 계속 잡아먹을 수 있을 것 같음. timeout 반드시 설정 필요함
