31 * NameOwnerChanged handling

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