It seems that PyEval_InitThreads() can no longer be called before
Py_Initialize(). I get a fatal error in PyThreadState_GET().
This contradicts the documentation

http://docs.python.org/release/3.2/c-api/init.html#PyEval_InitThreads

Minimal repro:

#include "Python.h"
int main()
{
     PyEval_InitThreads();
     return 0;
}

Everything works if Py_Initialize() is called first.
