Dear Jeff,

Right, so I really would have wanted OpenBLAS 
to be as reproducible as regular BLAS in this 
one random example, but my hands remains tied 
on this since I do not know anything about 
BLAS ... 

More interestingly, could you dream up any 
idea as to what might cause this difference?

Best,
Rasmus
