Comment(by oxygene):

 As far as I know, power-off works by writing to an IO-port and then wait
 for the system to shut down.

 The only alternative would be to write the message ("It's safe to shut
 down your computer"), then do the power-off routine, so that the message
 is visible in case the system does not shut down.

 Returning to the prompt would require the system to return some kind of
 error condition, so that filo knows that the system does not intend to
 cease operation.

 Of course, fixing power-off itself is part of the solution, too... (see
 drivers/intel.c, platform_poweroff)
