Comment(by wdj):
I applied only the 2nd patch to 4.1.1.a0. It seemed to work fine trying
out several examples form the docstrings by had. However, on an intel
macbook running 10.4.11 there were several failures of sage -testall:
{{{
sage -t "devel/sage/doc/en/bordeaux_2008/birds_other.rst"
sage -t "devel/sage/sage/calculus/interpolators.pyx"
sage -t "devel/sage/sage/interfaces/psage.py"
sage -t "devel/sage/sage/interfaces/sage0.py"
sage -t "devel/sage/sage/parallel/decorate.py"
sage -t "devel/sage/sage/symbolic/expression.pyx"
}}}
Some of these are probably spurious but some are not:

This looks like numerical noise but I'm not sure. In any case, it is in a
file you modified, so it
is probably not spurious.
