  Modified files:
    sys/kern             vfs_vnops.c 
  Log:
   - Do a vn_start_write in vn_close, we may write if this is the last ref
     on an unlinked file.  We can't know if this is the case until after we
     have the lock.
   - Lock the vnode in vn_close, many filesystems had code which was unsafe
     without the lock held, and holding it greatly simplifies vgone().
   - Adjust vn_lock() to check for the VI_DOOMED flag where appropriate.
