One should generally continue iterating until a suitable relative (or
absolute) residual norm is reached, with correspondingly small Newton
stepsize norm (for nonlinear problems).  Reaching the max number of
linear solver iterations before one of these other goals is achieved
is probably best treated as a failure in a linear problem.  The max
number of iterations is just there to control how long  you are
willing to wait for an answer...
