  Log:
  Make contigmalloc(9)'s page laundering more robust.  Specifically, use
  vm_pageout_fallback_object_lock() in vm_contig_launder_page() to better
  handle a lock-ordering problem.  Consequently, trylock's failure on the
  page's containing object no longer implies that the page cannot be
  laundered.
