  43 **      Device `dev1' is damaged in an amount `dam'.  Dam is measured
  44 **      in stardates, and is an additional amount of damage.  It should
  45 **      be the amount to occur in non-docked mode.  The adjustment
  46 **      to docked mode occurs automatically if we are docked.
  47 **
  48 **      Note that the repair of the device occurs on a DATE, meaning
  49 **      that the dock() and undock() have to reschedule the event.
