Note: Due to the distributed nature of the queue, a weighted random set of machines is sampled on a ReceiveMessage call. That means only the messages on the sampled machines are returned. If the number of messages in the queue is small (less than 1000), it is likely you will get fewer messages than you requested per call to #receive_message. If the number of messages in the queue is extremely small, you might not receive any messages. To poll continually for messages, use the #poll method, which automatically retries the request after a configurable delay.
