Fix some of the spelling issues. Fix sentences. Discourage SLOB use
since SLUB can pack objects denser.

SLOB replaces the SLAB allocator with a drastically simpler
allocator. SLOB is more space efficient that SLAB but does not
scale well (single lock for all operations) and is more susceptible
to fragmentation. SLOB it is a great choice to reduce
