Doug said that some people have recently been working on Boost.Signals and specifically addressed thread safety, but I'm not sure what the status of that is.
There is a working implementation by Frank Mori Hess in the boost sandbox under thread_safe_signals and another (which is currently not working) by me under signals. The efforts are discussed on the users list and everybody is welcome to contribute. I actually think that's what we need most in the current situation as providing thread-safety seems to be the least of our problems ;). For a quick summary: everybody agreed on dropping the "trackable" base class design as it cannot be made thread-safe. Besides that, compatibility with the current Boost.Signals has been maintained, even though it stands in the way of optimal scalability and also complicates the implementation. Independent design questions seem to fade away as quickly as they're raised, because of the lack of additional input. Regards Timmo Stange
