// Function that executes every Period  // msecs checking the registration list  // of synchronous tasks. Will induce a  // reset if any of the tasks fail to  // report an iteration within itıs    // ³registered² period or if a        // Terminate is requested.
// NOTE: Intended to be called from a  // thread or task, sole purpose is to  // service the watchdog, i.e.
// no ³return² from this function!
