+ The cache is not visible to the user. It should be flushed
+ when any file is closed or changes are made to the filesystem.
+
+ This cache implements a least-used-page replacement policy. This will
+ distribute sectors evenly over the pages, so if less than the maximum
+ pages are used at once, they should all eventually remain in the cache.
+ This also has the benefit of throwing out old sectors, so as not to keep
+ too many stale pages around.
