Ok, here's another version of Cells, attached. This one uses Agents,
like MikeM wrote. It works even on a 1-link chain of dependencies
-- see examples in the comment at the end. Cells get updated
asynchronously via actions on Agents. I may be missing some (dosync
...) wrappers in there.

"Actions dispatched to an agent from another single agent or thread

seems like this may be helpful, but since updates can occur from
