Yes, that's how I would answer my own question, too. It would be interesting
to see whether high-level components built on top of boost::thread can solve
the interthread communication problem in an elegant way. But if we focus on
the low-level layer, I think that this may be solved with a thread::target()
accessor (similar to the newly added function<>::target()).
