> Message age alert / notification only checks the age of the first message in
> the queue entry list.
> The housekeeping thread checks message status for each queue. During the
> process it iterates over given queue performing a notification check on each
> message (if it has not expired), however the actual notification check for
> message age ignores the message provided and simply requests the oldest
> message arrival time from the queue, then checks whether this time was before
> the limit imposed by subtracting the threshold time from the current time.
> The queue provides this time by getting the message at the head of the
> QueueEntryList and checking its arrival time. Moving or copying messages
> between queues using the management interfaces is one example of where the
> time provided by such a check may not actually be the arrival time of the
> oldest message on the queue, as moved/copied messages are enqueued at the end
> of the queue but may infact be older than those at the beginning of the queue.
