    Description

      Running some simple read and write tests using "dd" to large files I see a huge amount of memory allocated by the size-1024 slab - about 1/4 if all RAM of the system.

      The size of the per-page allocation must be reduced in some manner, since this is far to much memory wasted for CLIO overhead.
