Sorry, that was BS of course. It doesn't make sense to copy&paste the
PK querying code around into every single D-BUS service method in
order to use the async_callbacks interface. Even less so, since there
are two or three layers of other code in between the service method
and the PackageKit call. So for libraries like this, the async
frontend is pretty useless, and I guess I'm stuck with
#https://bugs.freedesktop.org/show_bug.cgi?id=14581 until I can go
ahead and actually use PackageKit :-(

So, please ignore my previous comment.

Martin
