/**
 * @assertion void kill({
 *    int priority: BEFORE_NEXT_EVENT
 *  })
 *   Requests the isolate to shut down.
 *   The isolate is requested to terminate itself. The priority argument
 * specifies when this must happen.
 *   The priority must be one of IMMEDIATE or BEFORE_NEXT_EVENT. The shutdown
 * is performed at different times depending on the priority:
 *      IMMEDIATE: The isolate shuts down as soon as possible. Control messages
 * are handled in order, so all previously sent control events from this
 * isolate will all have been processed. The shutdown should happen no later
 * than if sent with BEFORE_NEXT_EVENT. It may happen earlier if the system
 * has a way to shut down cleanly at an earlier time, even during the
 * execution of another event.
 *      BEFORE_NEXT_EVENT: The shutdown is scheduled for the next time control
 * returns to the event loop of the receiving isolate, after the current event,
 * and any already scheduled control events, are completed.
 *
 * @description Check that all previously sent control events are processed
 * before kill(IMMEDIATE) terminates the isolate, which waits for events.
 *
