 *
 * Note, we probably should do a core dump for the serious
 * signals such as SIGBUS, SIGPFE, ...
 * Also, for SIGHUP and SIGUSR1, we should re-read the
 * configuration file.  However, since this is a "general"
 * routine, we leave it to the individual daemons to
 * tweek their signals after calling this routine.
