  After a timeout XMemProxyCppUtilities::flushResponse
  gets an 0C4 abend because the acrw object being referenced is
  no longer an acrw object. The timeout processing had already
  freed the acrw object. If XMemProxyCppUtilities::flushResponse
  did not abend it would proceed to delete the acrw object which
  would be a double delete of the acrw object.
