Ryan Libby 27ca37acb7 uma: grow slabs to enforce minimum memory efficiency 
Memory efficiency can be poor with awkward item sizes (e.g. 1/2 or 1
page size + epsilon).  In order to achieve a minimum memory efficiency,
select a slab size with a potentially larger number of pages if it
yields a lower portion of waste.

This may mean using page_alloc instead of uma_small_alloc, which could
be more costly.
