While Emacs is idle, it blocks at the select() call in
wait_reading_process_output waiting for one of the several kinds of
events to happen: window-system events, subprocess output arrivals,
socket status changes, signal arrivals, and timer expirations. That's
why it is important to have a file/socket descriptor to monitor for
D-Bus in order to avoid consuming CPU time for polling.
As far as I browsed some D-Bus documents,
dbus_connection_set_watch_functions seems to have something to do with
this.
