Yes, I agree that using this word is a bit confusing.

Not sure what be a good alternative though. "Region", "block",
"collection", and "chunk" come to mind, but they don't reflect the
purpose/usage of these allocations as good as "slab". Although it's
possible that my perception as affected by overly frequently looking
at the slab allocator internals :)

Do you have a suggestion of a better word?
