I think we probably didn't think this through. Do you happen to know
whether ARPACK returns the number of iterations and final
residual/error? If so, then what we should probably call the check()
function with these values, ignoring the return code, just so that the
values are stored in the SolverControl object.
Want to give that a try and make it into a patch?
