There's absolutely no way you'd want multithreading on a BLAS1 
operation. It's not until BLAS3 that you become computation-limited.

In my opinion, we actually need matrices in the standard library, with a 
very small number of primitive operations built-in (much like Fortran 
does). Outside those, I agree, wrappers to an existing library should be 
used.
