+/**
+ * Mechanism for monitoring and controlling delivery of files to a destination.
+ * <p>
+ * The DeliveryQueue class maintains lists of DeliveryTasks for a single
+ * destination (a subscription or another data router node) and assigns
+ * delivery threads to try to deliver them. It also maintains a delivery
+ * status that causes it to back off on delivery attempts after a failure.
+ * <p>
+ * If the most recent delivery result was a failure, then no more attempts
+ * will be made for a period of time. Initially, and on the first failure
+ * following a success, this delay will be DeliveryQueueHelper.getInitFailureTimer() (milliseconds).
+ * If, after this delay, additional failures occur, each failure will
+ * multiply the delay by DeliveryQueueHelper.getFailureBackoff() up to a
+ * maximum delay specified by DeliveryQueueHelper.getMaxFailureTimer().
+ * Note that this behavior applies to the delivery queue as a whole and not
+ * to individual files in the queue. If multiple files are being
+ * delivered and one fails, the delay will be started. If a second
+ * delivery fails while the delay was active, it will not change the delay
+ * or change the duration of any subsequent delay.
+ * If, however, it succeeds, it will cancel the delay.
+ * <p>
+ * The queue maintains 3 collections of files to deliver: A todo list of
+ * files that will be attempted, a working set of files that are being
+ * attempted, and a retry set of files that were attempted and failed.
+ * Whenever the todo list is empty and needs to be refilled, a scan of the
+ * spool directory is made and the file names sorted. Any files in the working set are ignored.
+ * If a DeliveryTask for the file is in the retry set, then that delivery
+ * task is placed on the todo list. Otherwise, a new DeliveryTask for the
+ * file is created and placed on the todo list.
+ * If, when a DeliveryTask is about to be removed from the todo list, its
+ * age exceeds DeliveryQueueHelper.getExpirationTimer(), then it is instead
+ * marked as expired.
+ * <p>
+ * A delivery queue also maintains a skip flag. This flag is true if the
+ * failure timer is active or if no files are found in a directory scan.
