Re: [eigen] 2.0.16 and 3.0.1 for the end of the week.

We're seeing a dramatic slowdown for some code with 2.0.15 v. 2.0.10:
> Yes, when I use 2.0.10, the small piece of my test code uses "void Eigen::ei_cache_friendly_product<double>" for 137 times, while in the 2.0.15 case it is called for 1689 times!! This may be something peculiar in 2.0.15.

I'll try to get a small self-contained example to try with the 2.0.16 pre-release, but if the regression is still present, it might be worth holding off a little.
