Vienna RSS Reader user agent is making an influx of batched requests

Vienna RSS reader is flooding websites with multiple requests to feeds, which is causing a strain on resources.

Batch requests are being made from the Vienna RSS reader user agent for RSS feeds. But instead of the requests being made sequentially, they are being made at the exact same time. Not waiting a reasonable amount of time after a request before another is made hogs resources and notably slows down websites for other users.
