Research direction
Start with the CodSpeed benchmark for du_max_depth_balanced_tree in src/uu/du/benches/du_bench.rs, then trace the recursive safe_du function mentioned in the issue. Determine whether allocation can be improved with the system allocator; done means a measured improvement in the referenced benchmark without changing du behavior.
