What happens if py_dict is None or an empty dictionary?  The code still
does the wrong thing (it errors out if you have a one-element
dictionary, but not if you have a 0-element dictionary); furthermore, we
SHOULD allow a one-element dictionary (setting JUST seconds should do
the sane thing of passing 0 for nseconds, instead of erroring out).
Looking forward to v2.
