`Subreddit.new()` in a `while` loop without `time.sleep()` issues 2 or 3 GET requests per a second.

Describe the bug

It might not be a bug, but I’d like to let you know. Subreddit.new() in a while loop without time.sleep() issues 2 or 3 GET requests per a second. I think it’s too much. Since the README says "With PRAW there’s no need to introduce sleep calls in your code. ", beginners don’t include time.sleep() and it may annoy a remote server.

To Reproduce

> cat no_sleep.py 
import praw
import logging
logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(message)s', datefmt='%I:%M:%S')

reddit = praw.Reddit('nmtake')
while True:
    list(reddit.subreddit('redditdev').new(limit=1))

> python no_sleep.py 2>&1 | grep Fetching

Expected behavior

Not expected, but I hope PRAW sleeps automatically (say 1 second per a request) when a remote server doesn’t return Ratelimit headers.

System Info

• OS: Arch LInux x86_4
• Python: 3.8.4
• PRAW Version: 7.1.0

[Watchful1]

There were no sleeps at all. It was sending requests just as fast at the end as it did at the beginning. But I think that’s correct behavior by PRAW. If reddit doesn’t rate limit these types of requests, then there’s no point sleeping for them.

Thanks for the test! It’s okay as long as that behavior isn’t unexpected.
