alright. i made the function public and allow static call which has a 
positive side effect as you easy can flush a page cache from outside

flushing the rootline only:
t3lib_TCEmain::cacheHandler('pages', 0, 'language');

flushing a specific page from cache:
t3lib_TCEmain::cacheHandler('pages', 112, 'update');

hope that fits the needs.
