Celery SQS bug

1. Install dependencies with pip install -r requirements.txt
2. Fill up the queue by running python tasks.py 500
3. Start Celery with celery -A tasks worker --loglevel=INFO -c 3
4. Disconnect computer from internet until you receive a CANCEL_TASKS_BY_DEFAULT warning. This may take a couple minutes and you'll see several errors, but you have to wait until the warning.
5. Reconnect to the internet. After a couple seconds, Celery will reconnect and tasks will start flowing again.
6. Let tasks run for about a minute. You'll notice a slight slowdown and then suddenly tasks will stop entirely for a couple minutes, before resuming again.
