Make slab reclaim more aggressive

Many people have noticed that the kmem cache implementation is slow
to release its memory.  This patch makes the reclaim behavior more
aggressive by immediately freeing a slab once it is empty.  Unused
objects which are cached in the magazines will still prevent a slab
from being freed.
