1. State of a hardware or software
system that is deaf, dumb, and blind, i.e., accepting no input and
generating no output, usually due to an infinite loop or some other
excursion into deep space. (Unfair to the real Helen Keller,
whose success at learning speech was triumphant.) See also go flatline,
ill-behaved application which bypasses the very interrupts the
screen saver watches for activity. Your choices are to try to get
from the program's current state through a successful save-and-exit
without being able to see what you're doing, or to re-boot the
machine. This isn't (strictly speaking) a crash.
