I think yes, but the app can use the freed memory for other stuff. If the
memory held by KConfig is release early enough, there is a highly
probable that the app will allocate additional mem for it's own use...

BTW: QCache uses a list to keep the items, so you get the same complexity
as iterating the file over and over.
