Bug#492086: partman: menus are very slow

Humans percieve interactive things as "slow" if they take longer than
approximatly 0.1 seconds to respond. Increasing the speed of partman by
less than 50% is not going to yield a difference that is percievable to
humans. "slow" == "slow".

I mentioned a third one, that's easier to implement and test than either
of those (only needs a small modification to busybox, which already has
an option that does something very similar). Once someone has actually
implemented and tested it, or any other optimisation idea against the
actual code, and has actual numbers, we could think about actually applying
that optimisation.
