| * be prepared for the case where the application simply crashes |
| * and thus doesn't clean up properly. The way to handle this in |
| * DBus is to register for the NameOwnerChanged signal which will |
| * signal an owner change to NULL if the peer closes the socket |
| * for whatever reason. |
| * |
| * Handle this signal via a filter function whenever necessary. |
| * The code below also handles refcounting in case in the future |
| * there will be multiple instances of this subscription scheme. |
