Sorry if I'm responding slower than you write patches :-) But wouldn't 
it be simpler/cleaner just to instantiate the monitor with the name(s) 
that shouldn't count as busy?

Like this:

int rm_watch(
	rm_monitor **m,
	DBusConnection *connection,
	const char *device_name,
	rm_change_cb_t change_cb,
+	const char *dbus_unique_name, /* if the device is owned by this dbus 
name, don't consider it busy */
	DBusError *error);
