BTW, a +1 on moving concurrency in general towards an Erlang style model. It's much easier to program against. Yes, I know this is only being discussed for display management but it could be used for much more. (And that reminds me: on top of the rest of the list of things that lock up all of emacs unpleasantly which would be nice to have concurrency for: checking for package updates in a package manager.)
