Thanks for the links.  "tokyo" is interesting, though I fear the
intermediate matrix size regime where it really makes a difference will
be rather small.  My concern is in really tiny vectors, where it's not
even worth to call BLAS.

I try to solve this problem in some way or other.  I'll post here if I
end up with something interesting.
