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