  Log:
  Kick off the suspend sequence from the keyboard in a SWI rather than
  in the hardware interrupt context (even if it is likely just an
  ithread).  We don't document that suspend/resume routines are run from
  such a context and some of the things that happen in those routines
  aren't interrupt safe.  Since there's no real need to run from that
  context, this restores assumptions that suspend routines have made.
  
  This fixes Thierry Herbelot's 'Trying to sleep while sleeping is
  prohibited' problem.
