It will probably be a bit faster if you use PyList_SETITEM instead of
PyList_SetItem.  Since you're creating a brand new list, it's safe to
use the macro. (The macro just plugs in the new values, without
checking that the list is really a PyList, without checking for buffer
over/underflow, and without trying to decrease the ref count of an old
list item.)

As Alex already pointed out, you definitely have to check that neither
your list nor any of the PyLongs is NULL.
