When you use the PurgeQueue action, you can't retrieve any messages
deleted from a queue.
The message deletion process takes up to 60 seconds. We recommend waiting for 60 seconds regardless of your queue's size.
Messages sent to the queue before you call PurgeQueue might be
received but are deleted within the next minute.
Messages sent to the queue after you call PurgeQueue might be
deleted while the queue is being purged.
