 * <pre class="code">

 * // In the operation recovery/retry loop:
 * long waitInterval = exec.nextBackOffMillis();

 *     // sleep, e.g. Thread.sleep(waitInterval)
 *     // retry operation
 * }
 * }</pre>
 *
 * Once the underlying operation has completed successfully,
 * the execution instance can be simply discarded.
