What would this interface look like?
It seems to me having a grouped allocate and free interface allows for a
variety of implementations: either the -stable sample implementation Luigi
posted, a uma-based one in -current, or a modification of the -current
mbuf allocator. The gains from each implementation may vary, but is
no worse than doing the two allocations separately and returning them
as a group.
