 * When actors are closed, arg1 is priority, arg2 is handle of the "instance \r

 * In this case, the lower three bits is the object class of the instance finish \r
 * handle. The lower three bits are not used (always zero) when queues are \r

 * XTS Event - eXtended TimeStamp events\r
 * The timestamps used in the recorder are "differential timestamps" (DTS), i.e.\r
 * the time since the last stored event. The DTS fields are either 1 or 2 bytes \r
 * in the other events, depending on the bytes available in the event struct. \r
 * If the time since the last event (the DTS) is larger than allowed for by \r
 * the DTS field of the current event, an XTS event is inserted immidiatly \r
 * before the original event. The XTS event contains up to 3 additional bytes \r
 * of the DTS value - the higher bytes of the true DTS value. The lower 1-2 \r
 * bytes are stored in the normal DTS field. \r
 * There are two types of XTS events, XTS8 and XTS16. An XTS8 event is stored \r
 * when there is only room for 1 byte (8 bit) DTS data in the original event, \r
 * which means a limit of 0xFF (255). The XTS16 is used when the original event \r
 * has a 16 bit DTS field and thereby can handle values up to 0xFFFF (65535).\r
 * \r
 * Using a very high frequency time base can result in many XTS events. \r
 * Preferably, the time between two OS ticks should fit in 16 bits, i.e.,\r
 * at most 65535. If your time base has a higher frequency, you can define\r
 * the TRACE\r
