michael@0:  * Overview
michael@0:  * This service keeps track of a user's session, storing the various bits
michael@0:  * required to return the browser to its current state. The relevant data is
michael@0:  * stored in memory, and is periodically saved to disk in a file in the
michael@0:  * profile directory. The service is started at first window load, in
michael@0:  * delayedStartup, and will restore the session from the data received from
michael@0:  * the nsSessionStartup service.
