This user might have a version from before that was an error by default,
but maybe there should still be an option -mat_log_setvalues (or
-log_mat_setvalues?) that enables MAT_SetValues so they don't have to call
this advanced function to profile time in MatSetValues?

  /* Turn off high traffic events by default */
  ierr = PetscLogEventSetActiveAll(MAT_SetValues,
PETSC_FALSE);CHKERRQ(ierr);
