Looks reasonable if you don't need portability. But you may want to
refactor it a little bit to make sure terminal setting are always
restored:
try:
do_all_the_work()
finally:
os.system("stty cooked")
P.S. Maybe its me, but when I see call sys.exit() I always have a gut
feeling this function never returns. But in fact my I'm wrong and
sys.exit is more reasonable: it raises exception. So you can call
sys.exit() inside do_all_the_work and you can still be sure that
os.system("stty cooked") is always executed at the end.
