Maybe not for headerfiles, but if you have an indexed database 
representing a compiled framework (partial evaluation/incomplete 
type support in templates) it should pay off if you preload the 
pages you need to access. If you run low on memory it also means 
you don't have to save pages to disk, the OS can just evict them.
