36  * a signal that it needs. While it can also unregister, we must
37  * be prepared for the case where the application simply crashes
38  * and thus doesn't clean up properly. The way to handle this in
39  * DBus is to register for the NameOwnerChanged signal which will
40  * signal an owner change to NULL if the peer closes the socket
41  * for whatever reason.
42  *
43  * Handle this signal via a filter function whenever necessary.
44  * The code below also handles refcounting in case in the future
45  * there will be multiple instances of this subscription scheme.
