Ok, so much for the easy hack.

What you say above has other sinister overtones as well - an
application that is listening to frequent dbus signals has no way of
getting swapped out, or staying swapped out (it can stay mapped in for
days without doing any useful work at all).

I don't think real applications out there have a habit of
unsubscribing from dbus signals when they don't need them either.
