Yeah, needs to be fixed.
Meanwhile, I just committed a small change which makes *top*
a bit more useful in this regard: now you can feed it input by pipe:
echo .m.s.s.s.s.s.s.q | busybox top -b
and it will execute it as if it is entered from keyboard.
"." is an invalid key, here is causes top to generate
one iteration of output.
