As a follow up to
APLO-76, it would be nice if a full queue could be safely handed to something which could walk the queue and make raw, intelligent changes to it.
Scenario: A ptp queue has multiple types of events in it and becomes full due to a slow consumer. Being able to walk the queue would allow dropping all events of a specific type in the queue and replace the first one in the queue with an event which effectively says to the consumer that they have missed events of a specific type and require to resync. The "walking", resync and replacement event would be application specific.
