Not sure if keeping unitized structure is a good solution in the long
run. However if you are aiming for performance instead of:

```
+   /* Clear fields that cost_material() will consult */
+   matpath.parallel_workers = 0;
    matpath.parent = NULL;
```

... you could just rewrite the `if` condition in cost_material():

```
    if (path->parent != NULL && /* <--- is false */
        path->parallel_workers == 0 &&
```
