And just to clarify: by "what speeds up, and by how much", I do _not_ mean "sending a dbus message speeds up by 10x and avoids context switches". I've seen _those_ numbers. But does it actually matter? It was more of a "there are thousands of dbus messages during boot, but can you actually measure the speedup?" question. That's the kind of numbers I've not seen.
