SVN rev 207519 on 2010-05-02 16:44:06Z by alc
This change addresses the race condition that was introduced by the previous
revision, r207450, to this file. Specifically, between dropping the page
queues lock in vm_contig_launder() and reacquiring it in
vm_contig_launder_page(), the page may be removed from the active or
inactive queue. It could be wired, freed, cached, etc. None of which
vm_contig_launder_page() is prepared for.
