I want my service to free the memory when it is not used. 
Use case: 
	- daemon that creates the service is auto-launched by D-Bus when the first client connects to it
	- client finishes with the service
	- daemon should auto-close - nobody is using it

My problem: I do not know when I have clients connected to my service. I was hoping that D-Bus offers this functionality. 
If not, should I implement such an API into my service, something like: Client calls addRef when it connects and calls unref when its done?

Thanks a lot,
