 // The Watchdog class creates a second thread that can Alarm if a specific
 // duration of time passes without proper attention.  The duration of time is
 // specified at construction time.  The Watchdog may be used many times by
 // simply calling Arm() (to start timing) and Disarm() (to reset the timer).
 // The Watchdog is typically used under a debugger, where the stack traces on
 // other threads can be examined if/when the Watchdog alarms.
