I don't know the "N" format, but if Py_BuildValue returns a new reference,
you're leaking a reference to the L list.
Why don't you return L directly?
You can use sys.getrefcount in Python to see the reference count for an
py> from sys import getrefcount as rc
py> x = object()
2 # the name x, and a temporary reference as parameter
1 # only the temporary reference
py> x = y = 
py> x = ()
954 # the empty tuple is shared
