Much of the Objects chapter is based on using Damian's Class::StdOne problem with Class::Std is that it is not 'thread safe' (and hence not 'fork safe' under Win32).
While this may be an oversight, it could also be intentional as the book doesn't talk about threads at all.
xdg presents a mechanism whereby thread-safety can be introduced into an inside-out object model, and I have successfully used it in Math::Random::MT::Auto. Hopefully, TheDamian will incorporate xdg's concept into a future release of Class::Std.
