More details in the OpenCL specifications at section 5.9.
	 * @param executionStatus specifies the new execution status to be set and can be CL_COMPLETE or a negative integer value to indicate an error. A negative integer value causes all enqueued commands that wait on this user event to be terminated.	setStatus can only be called once to change the execution status of event.
