this might be a bug. Not many applications are actually making full use
of the DeviceDisappeared signal. Please run dbus-monitor and check if it
is really not present.
On another note, you can _NOT_ hardcode /org/bluez/hci0 path in your
apps. Nowadays they are totally random. Use FindAdapter() instead.

Marcel
