I think this part would be simpler (and require loading less memory) if written like this (like in pbvh_update_normals_store_task_cb):

const int *verts = node->vert_indices;
const int totvert = node->uniq_verts;

for (int i = 0; i < totvert; i++) {
  const int v = verts[i];
  MVert *mvert = &pbvh->verts[v];
  if (mvert->flag & ME_VERT_PBVH_UPDATE) {
    zero_v3(data.vnors[v]);
  }
}

Thanks, I hadn't touched sculpt code in a while and missed the possibility of looping over verts directly. In this case though, there are no problems accessing from multiple threads.

Great, even better!
