Well, the app is multi-threaded, so I do have a big issue getting
control back to my C program.  I just can not seem to cleanly stop the
interpreter.  The best I could do is:

void terminateInterpreter( PyInterpreterState *interp )
{
PyGILState_STATE gilstate;
PyObject *exc;
PyThreadState *tstate;

gilstate = PyGILState_Ensure();
tstate = PyThreadState_Swap(interp->tstate);

exc = PyString_FromString("Die");
PyThreadState_SetAsyncExc(interp->tstate->thread_id, exc);
Py_DECREF(exc);

PyThreadState_Swap(tstate);
PyGILState_Release(gilstate);
}

Nope, not yet.  That would have been my next post :-)  I thought there
would have been much more work on cross-compiling and porting Python.
I may need to reconsider if Python is appropriate; the other
possibiities are javascript or lua.
