The proposal from Richard was to use IPC between the UI bits and the
actual mechanism (yum, apt, whatever) that carries out the work. So the
UI client would be a simple single-threaded process that just calls into
a D-Bus system service. Async calls doesn't mean multithreaded, it can
also means callback from a mainloop. Nothing new here.
