- BookNavigationBlock 
  - menu_get_object() called from build, in search of a node
	- book_get_books() called, if in "all pages" mode, to search out book/current page associations
	- lots of menu_tree_output(), etc., called, which relies on current path info

- ActiveTopicsBlock and NewTopicsBlock
	- not breaking data encapsulation, but calls drupal_render_cache_by_query()

- LanguageBlock
	- menu_is_front_page()/current_path()
