SVN rev 202529 on 2010-01-17 21:26:14Z by kib
When a vnode-backed vm object is referenced, it increments the vnode
reference count, and decrements it on dereference. If referenced object
is deallocated, object type is reset to OBJT_DEAD. Consequently, all
vnode references that are owned by object references are never released.
vunref() the vnode in vm object deallocation code for OBJT_VNODE
appropriate number of times to prevent leak.
Add an assertion to the vm_pageout() to make sure that we never get
reference on the vnode but then do not execute code to release it.
