We didn't measure it for real yet, but during my tests it was quite
similar with the previous version. I also had the impression it was
slower, but when comparing both I got basically the same 30 seconds to
boot.

Once we have the upstart android bridge we'll get rid of most races we
currently have, and as a consequence we should have a faster boot as
well (no more sleeps all around). Then we can start looking at some
more optimization as well.
