I don't see such signals, and this can be a real problem. libqsystemd
currently implements caching for values because I consider D-Bus calls
expensive, but there is nothing that would invalidate cached values.

That's possible, though the default setup of the D-Bus service grants
this right only to root. Sounds like a job for PolicyKit.
