The main thing that I know is not thread safe is the use of reference counted pointer for variable in the C++ code. So, the creation/destruction of variables may require...

@lysnikolaou Thanks for shimming in. As I mentioned earlier the C++ code use reference counted pointer which are not thread safe so a minimal protection is required. A global lock...
