32 * NameOwnerChanged handling

35 * a signal that it needs. While it can also unregister, we must
36 * be prepared for the case where the application simply crashes
37 * and thus doesn't clean up properly. The way to handle this in
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.
