But if we rule out closed-source BLAS, and we rule out OpenBLAS
because of our distrusting its accuracy, and we aren't going to
recompile ATLAS on every machine, then Eigen is the only library they
tested that is even an option for us.

It would be nice to see some comparison between our actual options --
Eigen, generically compiled ATLAS, anything else?
