You only need to call PyEval_InitThreads() once in the main Python thread.
This is not well documented. For your information, PyGILState_Ensure() now calls PyEval_InitThreads() in Python 3.4, see: http://bugs.python.org/issue19576
I did see that - but from my own experience, I do not believe it is calling PyThreadState_New(..) and it is not even checking if PyThreadState_New(..) has ever been called for the active thread Consequently, the thread is blocked or there is a seg fault I've now written up a much more thorough overview of my experience on my blog: http://danielpocock.com/embedding-python-multi-threaded-cpp
