michael@0	8	* What this is aimed to test:
michael@0	9	*
michael@0	10	* Expiration will obey to hardware spec, but user can set a custom maximum
michael@0	11	* number of pages to retain, to restrict history, through
michael@0	12	* "places.history.expiration.max_pages".
michael@0	13	* This limit is used at next expiration run.
michael@0	14	* If the pref is set to a number < 0 we will use the default value.
