BeOS definitely had a block cache. If BFS hadn't use it, it would probably 
have been even slower. :-) I would also doubt that BFS used it only for 
some things and not for others (not considering the superblock), as the 
only alternative I can think of is accessing the disk directly, and I can't 
come up with a reason to do that, save for slowing things down deliberately.
