    *                      fix a problem in recording the location*
    *                      of AGGIMSLI when it was previously     *
    *                      loaded by AGGRRC00 for another task.   *
    *                      Logic in AGGRRC01 was changed to       *
    *                      monitor shutdown requests from AGGRRC00*
    *                      before requesting STIMER pauses in an  *
    *                      @FRHP loop, much like what was being   *
    *                      in an outer loop which called @FRHP.   *

    *                      tracing through IMS data structures    *
    *                      (probably while they are asynchonously *
