patches from SciPy

[lucascolley]

Hi @felixlen, would you be interested in taking on patches from SciPy, such that we could have a more sane vendoring situation, where there is just one copy of the code to be maintained rather than two?

I think it would be great, so that any fixes you make here will propagate to SciPy users, and any SciPy contributors sending fixes will be redirected here.
