This is a variable metric method I implemented for 3.2; it is usually
more efficient than CG, but it involves an iterative step that we
haven't bothered to parallelize. CG is significantly improved in 3.2,
too (and it works in single too, now).

I'm pretty sure I added it to the manual, but tell us if it's not
there. Both CG and BFGS are Newton-style generalized methods for
