appear: when freeing a modified page, it wouldn't have a cache
  anymore, but set_page_state_nolock() depended on it.
* To work around this, I added a vm_page_free() function, which the
  caches that free modified pages have to call (but others may, too).
  It will correctly maintain the sModifiedTemporaryPages counter in case
  the cache has already been removed.
