  SVN rev 218164 on 2011-02-01 10:20:31Z by kib
  
  MFC r217824:
  When vtruncbuf() iterates over the vnode buffer list, lock buffer object
  before checking the validity of the next buffer pointer. Otherwise, the
  buffer might be reclaimed after the check, causing iteration to run into
  wrong buffer.
