- * @short_description: helper program during a restart
- *
- * To smoothly restart Mutter, we want to keep the composite
- * overlay window enabled during the restart. This is done by
- * spawning this program, which keeps a reference to the the composite
- * overlay window until Mutter picks it back up.
