The vm_page_wire function increments the wire count on a page, and removes it from whatever queue it is on.
The vm_page_unwire function releases one of the wirings on the page. When write_count reaches zero the page is placed back onto either the active queue (if activate is non-zero) or onto the inactive queue (if activate is zero). If the page is unmanaged ( PG_UNMANAGED is set) then the page is left on PQ_NONE.
