you think async downloads will actually be all that much of an
improvement? As a test setup entirely local-disk repositories and run a
chroot install, compare that to a fast network and see where the
bottlenecks are.

I'm curious of the results.

The biggest objection I've had to async downloads/parsing is that you
end up having a very confusing callback interface to track what is being
downloaded and when. Your thoughts on correcting that?
