I guess "working correctly" for cyclic dependencies means you need to introduce the concept of time and be careful to update everything in the proper moment? What is this useful for?

See http://research.microsoft.com/apps/pubs/default.aspx?id=211297 http://research.microsoft.com/apps/pubs/default.aspx?id=2112... if you haven't already. I have both time and phases; time is used for versions and discrete updated via event handling; phases are used to ensure state doesn't get "stuck" in a cycle on a non-monotonic change. Rollback is used instead of carefully updating anything in the right order, phases however suppress when updates can be seen during processing. It's generally useful for writing reactive, incremental, iterative programs.
