I think, the `dealloc` function is responsible to actually
free the memory area.

I see for example:
static void
Spec_dealloc(Spec* self)
{
    /* PyType_GenericAlloc that you get when you don't
       specify a tp_alloc always tracks the object. */
    PyObject_GC_UnTrack((PyObject *)self);
    if (self->weakreflist != NULL) {
        PyObject_ClearWeakRefs(OBJECT(self));
    }
    Spec_clear(self);
    Py_TYPE(self)->tp_free(OBJECT(self));
}
