Ah, right. Yes it does. That seems rather tricky to implement. 
I just had a little try on it and I noticed that in order to interrupt the thread calling the blocking wait one would need this thread's boost::thread object. Which cannot be obtained from the this_thread::id. So each thread calling that interruptable receive would have to have it's boost::thread object to pass it to the function, right? 
I can't see how I could expose all this to the interface of this method. I think it has to be closer to asio.

Cheers,
