    Add debug hack to intentionally slow down tile rendering
    
    When compiled with --enable-debug, when requesting a tile for part=42,
    actually use part=0, and sleep five seconds before passing the
    rendered tile back up. This makes it easier to debug handling of
    simultaneous requests for the same tile from multiple clients.
