This could be fixed by first releasing the service name synchronously,
then processing all queued requests and only then closing/exiting.

Hmm, will bluetoothd also be started via bus activation? If so, it
wuld probably make sense to issue a StartByName D-Bus request from the
udev rule and let dbus handle all the ordering/synchronization issues
with starting up bluetoothd.

I know at least one application (PA) that wouldn't reconnect to coming
and going bluetoothd's, that's why I am asking.
