History
Attilio Rao 0d8243cc34 vm_page_grab() and vm_pager_get_pages() can drop the vm_object lock, 
then threads can sleep on the pip condition.
Avoid to deadlock such threads by correctly awakening the sleeping ones
after the pip is finished.
swapoff side of the bug can likely result in shutdown deadlocks.
