SVN rev 191204 on 2009-04-17 15:35:16Z by alc
MFC r175055
Defer setting either PG_CACHED or PG_FREE until after the free page
queues lock is acquired. Otherwise, the state of a reservation's
pages' flags and its population count can be inconsistent. That could
result in a page being freed twice.
(This change should have been included in the MFC of the superpages
support.)
