Happened while testing certain Mindwork software under Haiku. At the point, the system was running for over 7 hours and downloaded over 4 GB of playback objects. The caches were utilising a good chunk of the 2 GB of memory, the player was just launching, so I guess the system was trying to free no more used cached pages to make room for the player.
Don't know yet if it is easily reproducable.

Oops, that was a bit too early - I actually only fixed a theoretical bug (it would only be a problem if the page_writer would ever quit, which it never does).
Bug #1926 is a duplicate of this one, and contains a slightly different stack crawl.
