See Freund & Nachtigal p.329. What criterion should we use for the transfer? Residual? Error? Other?

For beginning, transfer based on residual norms could be interesting. We just need to compute exactly the residual norms of QMR for that. #156

Yes, or we could use a residual estimate to begin with.
