+/**
+ * Session Storage and Restoration
+ *
+ * Overview
+ * This service keeps track of a user's session, storing the various bits
+ * required to return the browser to its current state. The relevant data is
+ * stored in memory, and is periodically saved to disk in a file in the
+ * profile directory. The service is started at first window load, in
+ * delayedStartup, and will restore the session from the data received from
+ * the nsSessionStartup service.
