If the SNESFunction computes NaN because the state is invalid, please
call SNESSetFunctionDomainError and don't update the residual vector (or
don't put NaN in there).  SNES will clean up and return with
SNESConvergedReason SNES_DIVERGED_FUNCTION_DOMAIN.

We don't do this by default because detecting NaN collectively requires
an extra reduction.  Perhaps SNES could have a mode that automatically
checks.

> The issue is that when SNES diverges with a "not-a-number or infinite", the code crashes without giving timestepper_BE a chance to reduce the time-step. But, if CHKERRQ() is commented out after call to SNESSolve(), the code is able to reduce dt sufficiently to converge due to "itol_res" (PFLOTRAN's custom convergence reason == inorm_residual < solver%newton_inf_res_tol). Attached below is inputdeck (with an outrages initial dt = 1yr to illustrate the issue). Apart from commenting out CHKERRQ(), is there an alternate way to let timestepper_BE reduce dt?
