Assuming we are using Thomas' patch that already removed the vm_page_wire()
from the earlier for loop, then at the point of this VM space allocation
failure, we haven't done anything too serious to the vm_page nor to the pmap,
nor are they in any object. We should be able to simply place it back to the
colored free list, something as easy as:
*** vm_page.c Mon Oct 15 10:26:14 2001
--- vm_page.c.new Mon Oct 15 11:32:46 2001
***************
*** 1934,1939 ****
--- 1934,1942 ----
* above available.

vm_map_unlock(map);

splx(s);
return (NULL);
