     36  * be prepared for the case where the application simply crashes

     38  * DBus is to register for the NameOwnerChanged signal which will
     39  * signal an owner change to NULL if the peer closes the socket
     40  * for whatever reason.
     41  *
     42  * Handle this signal via a filter function whenever necessary.
     43  * The code below also handles refcounting in case in the future
     44  * there will be multiple instances of this subscription scheme.
