4BSD does both.  Prepaged pages are put on the free list and are
available for reclaiming when referenced.  The clustering is called
`klustering' to distinguish it from 4BSD's other kind of clustering,
which is simply treating several hardware pages as though they were a
single page, to compensate for the small page size on the Vax.
