i have to admit that i didn't found the place where $typo3CacheFactory 
gets $GLOBALS['typo3CacheFactory'] - the global is some kind of magic 
where i stumble often.
But indeed the init is done only in init.php and unsetting throws this 
fatal error in BE (for me too).
Don't know - bad by design or bad documented.
