Smart does this with "upgrade --stepped" (normally you want a
--yes in there too, so that you don't have to confirm each...)

It is very useful for large upgrades when you are short on
disk space, since it doesn't have to download all packages.
Instead it downloads as many as is needed for each transaction,
installs/upgrades them, and then deletes the cached packages.

Unfortunately it is not yet available in the graphic interface,
so not many know about it. (But it's in the help, and the manual)
