You want something like:

       void operator() (double time, const AudioData&data) {
           PyGILState_STATE old = PyGILState_Acquire();
           m_Function(time, data);
           PyGILState_Release(old);

Note that Phillip is also correct; you will need to initialize threading 
if this is an app which embeds Python...

HTH,
