o  events lost

    Generated whenever the event dispatcher cannot allocate resources
    to queue more events for processing. The event-logging function
    guarantees that this event cannot be lost. Also, you cannot block
    this event unless all events for all modules are blocked.

    This event is placed at the end of the queue. If another event
    cannot be queued because of resource limitations while this event
    is still the last event in the queue, the number argument is
    updated to reflect the latest total of lost events.  Argument:

    number         Number of consecutive events lost.

 o  test requested

    Logged when the test directive is issued.
