- Resolve bucket recursion issues by passing a cookie with zone flags
through bucket_alloc() to uma_zalloc_arg() and uma_zfree_arg().
- Make some smaller buckets for large zones to further reduce memory
waste.
- Implement uma_zone_reserve(). This holds aside a number of items only
for callers who specify M_USE_RESERVE. buckets will never be filled
from reserve allocations.
