Committed small patch to allow 2 extra passes

> The conjugate gradient solve that we have assumes that it will converge
> within the theoretical n steps where n is the size of the input. In fact,
> convergence may not happen within exactly that number of steps due to
> numerical issues so we should allow for a few extra iterations.
