    ierr = PetscOptionsBool("-ts_theta_adapt","Use time-step adaptivity with the Theta method","",th->adapt,&th->adapt,NULL);CHKERRQ(ierr);

   Really, even a method so simple minded I can understand it, requires its own flags for adaptivity?

   Based on this model we'll have -ksp_cg_max_its and -ksp_gmres_max_its pretty soon and where is -ts_arkimex_max_steps, we'd better add it soon.
