In the instancemethod_setattro function, it might be nice to do the speed
optimization and test for sname[0] == 'i' before hitting the strcmp()
calls.

Oh: policy question: I would think that these attributes *should* be
available in restricted mode. They aren't "sneaky" like the builtin
attributes.

Rather than PyMapping_Get/SetItemString()... PyObject_Get/SetItem() should
be used. They apply to mappings and will be faster. Note that (internally)
the PyMapping_Get/SetItemString use the latter forms (after constructing a
string object(!)).
... whoops. I see that the function object doesn't use the ?etattro()
variants. hrm.

The stuff is looking really good!
