/**
 * AmazonSQSBufferedAsyncClient provides client-side batching of outgoing sendMessage, deleteMessage
 * and changeMessageVisibility calls. 

 * After receiving a call, rather than executing it right away, this client waits for a configurable
 * period of time ( default=200ms) for other calls of the same type to come in; if such calls do
 * come in, they are also not executed immediately, but instead are added to the batch. When the
 * batch becomes full or the timeout period expires, the entire batch is executed at once and the
 * results are returned to the callers. This method of operation leads to reduced operating costs
 * (since SQS charges per call and fewer calls are made) and increased overall throughput (since
 * more work is performed per call, and all fixed costs of making a call are amortized over a
 * greater amount of work). The cost of this method is increased latency for individual calls, since
 * calls spend some time waiting on the client side for the potential batch-mates to appear before
 * they are actually executed. 

 * This client also performs pre-fetching of messages from SQS. After the first receiveMessage call
 * is made, the client attempts not only to satisfy that call, but also pre-fetch extra messages to
 * store in a temporary buffer. Future receiveMessage calls will be satisfied from the buffer, and
 * only if the buffer is empty will the calling thread have to wait for the messages to be fetched.
 * The size of the buffer and the maximum number of threads used for prefetching are configurable. 

 * AmazonSQSBufferedAsyncClient is thread-safe.
