* src/eventsurrender.c: The problem here is that events may be lost
when sent to a task which enters rtems_event_receive() with options
set to wait with a timeout and to return on receipt of any event. The
events are sent from an interrupt source such as a timer service
routine. If more than one set of events is sent to the task before it
returns, the first event set may be overwritten.
