Hmm, I don't think we're out of the woods yet. I think we're hitting
a very short cycle problem of Visual Studio's rand LCG that won't show
up using GCC on Linux.

We may need to use rand_s() on Windows.

I just sent a follow up note to your previous one. I don't have a
Windows dev box or I'd help test this.
