* @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 kill(priority: Isolate.beforeNextEvent) doesn't
* terminate the continuously running isolate
