    initial v2  
    1 Based on the scoped_thread class defined in C++ Concurrency in Action define a thread wrapper class that instead of calling terminate if the thread is joinable on destruction, interrupts and join it if joinable.

     3While the scoped_thread class defined in C++ Concurrency in Action is a strict scoped class that doesn't allows any change in the wrapped thread, I think that making the interface thread compatible is also a good option. This doesn't means that a strict scoped thread has no use.
