This will help our resource usage issues as well as Owen's gnttab work. I have
checked, and unless he modified more source files, this does not currently
conflict with anything Owen has in the works.
Approved, MCH.

To avoid a large overhead in both time and potemtially space when a new slab is
created, only construct objects as they are allocated. When they are freed we
keep them constructed to increase the chance of finding an already- constructed
object during subsequent allocations.
