Well, do *all* ref-counted objects have to be thread-safe though? Making stuff thread-safe comes with an overhead, and in some code thread-safety isn't really guaranteed, like Calc core. We currently require the caller to ensure that multiple threads aren't accessing the core implementation, which basically translates to a bunch of solar mutex objects in the UNO API implementations... So, when we are implementing ref-counted objects in such code, I'd like not to have the overhead of thread safety.
