No, but similar code is already in Nautilus [see
nautilus-monitor.c:monitor_add_internal()]. I'm not sure putting it in
gnome-vfs for all monitor uses is a good idea. It imposes a quite heavy
performance hit (stat per monitor + need to connect to the daemon for
the volume monitor) for things that rarely need this. And it doesn't
even really "solve" anything. If an app leaves monitors around it'll
still mean you can't unmount the volume, and this needs fixing anyway.
