I'm not familiar enough with the implementation of uBlas to understand
what's happening here. However, I think I proved in my recent posting that
no temporaries are neccessary, and that you might want to *consider* using
them for A*(B*v) to reduce the number of writes. It wasn't clear to me
how/whether you were responding to that post, though...
