I really should submit a patch for that documentation, at least illustrating
the techniques that I've used.

The original reason to switch to an asynchronous service-side implementation
was so that control could be passed back to the main loop, otherwise the
system-image service -- which also acts as a client of ubuntu-download-manager
-- couldn't react to signals coming from u-d-m.  With a synchronous
ApplyUpdate() method, everything would just deadlock.
