Reference Counts & Extensions..

Hi,

    I'm writing an extension module and in my functions I return something
like:

    return Py_BuildValue("i", 1);

    Will this cause a memory leak?  Should I be doing this:

    PyObject *pyObj = PyBuildValue("i", 1);
    Py_INCREF(pyObj);
    return pyObj;

    Also, what if I make pyObj a global variable, can I then use the first
method since the reference will be borrowed, like so:

    return pyObj;

Thanks,

John
