  "message": "Simplify IterativeRefiner\n\nChange the loop structure of IterativeRefiner to\nunconditionally refine for max_num_iterations.\n\nThis is done for two reasons.\n\n1. We expect to use this refinement for a small number of iterations\n   where the convergence test is useless.\n2. Eliminating the convergence test means we can restructure the loop\n   and save on a sparse matrix-vector multiply, saving precious\n   compute.\n\nChange-Id: I6347f453a5d19d234af2a2eb1bce811048963e06\n",
