There really is no way around this, except either to rewrite the
maximiser in a language that allows reentrancy ( = C in practice) or
wait for someone to write a Fortran compiler that does. We've
previously done this for the solvers, and nlm appears to be under
scrutiny at the moment anyway, so perhaps...
