[boost] smart_ptr and handles

Dear group, is it possible to use smart_ptr with handles ( e.g. HWND, HBRUSH, HDC, etc )? Wouldn't it be quite convenient to have something like a scoped or shared resource? The idea came when I looked my OpenGL initialisation code, where I have to free the resource explictly every time an error occurs, which make the code somehow a little bit more difficult to read and I though that it would be nice to have some kind of RAII mechanism here.
