I would guess the failure is because the message from client 2 has
already been queued for your service process when your service process
exits?

In that case the solution I can think of is to first drop ownership of
the bus name, then process your incoming queue, _then_ exit.

You might need the bus to support some kind of "deliver all my queued
messages, then disconnect me" feature.

Also I don't remember if the "disown bus name" patch went in yet.

Anyway, just write down exactly what race condition happens and the
solution is probably pretty clear, though it may involve changing dbus.
