Well, the intended operation is something like this:

InstallPackage(foo)
::status(depsolving)
copy file1, file2, file3 from media
::media-change-required
::error

and then the client handles the new media request, and then re-queues
the request as a new transaction:

InstallPackage(foo)
::status(depsolving)
copy file4, file5, file6 from media
::status(installing)
::finished

So we actually deal with two transactions, and when we're waiting for
the user to find the correct disk and click ok, we're not blocking the
daemon so other things can happen. This is very similar to how the
trusted "wiggle" happens and is described in more detail here:

It should work with git versions of PackageKit and gnome-packagekit already.
