  SVN rev 216807 on 2010-12-29 20:35:36Z by alc
  
  There is no point in vm_contig_launder{,_page}() flushing held pages,
  instead skip over them.  As long as a page is held, it can't be reclaimed by
  contigmalloc(M_WAITOK).  Moreover, a held page may be undergoing
  modification, e.g., vmapbuf(), so even if the hold were released before the
  completion of contigmalloc(), the page might have to be flushed again.
