OK. I'm finding the relevant interfaces in Python/C API.
Do I read this right, that all new objects are created 
with a refcount of 1 , so that a called function
can pass them to the caller without ref-count manipulation?
Thus, I can call PyList_New() to create the list that will
be returned to the calling Python procedure, iteratively
pass the results of PyTuple_New() directly to 
PyList_SetItem(), which "steals" the reference to the 
tuple, and then return the list, all without a single 
INCREF or DECREF? Which, of course, is the way it *ought* 
to work, and that seems to be what it says ..
