I think I mentioned one good example where it is very useful before. When
battery is already very low, maybe something like < 3%, and I know I will
send the system to sleep for only a short time, but I don't know if 3%
will be enough until I will get my hands on a AC adapter 10 minutes later,
I like to do s2both to be on the safe side.
