Note that there is discusion right now on pyton-dev about requireing SSE2
for teh python.org build of python3.5 -- it does now, so it's fine for
third party pacakges to also require it. But there is some talk of removing
that requirement -- still a lot of old machines around, I guess --
particular at schools and the like.

Ideally, any binary wheels on PyPi should be compatible with the python.org
builds -- so not require SSE2, if the python.org builds don't.

Though we had this discussion a while back -- and numpy could, and maybe
should require more -- did we ever figure out a way to get a meaningful
message to the user if they try to run an SSE2 build on a machine without
