What?  Who corrupts them?  That shouldn't be possible, and on some
systems, even if you do ask for a separate slab, it will be merged
togther with others of the same size.  So this patch doesn't do all that
much.

I think you are having some other problem here, changing to a separate
memory cache shouldn't solve corruption issues.
