Regions with many nearby points keep subdividing. Regions with few or no points stay large. The tree adapts to the data: dense areas get fine-grained cells, sparse areas stay coarse. The split grid is predetermined (always at midpoints), but the tree only refines cells that need it. Sparse regions stay as single large nodes while dense regions subdivide deeply.
Cgroups are important for stability, but they are not a security boundary. They prevent denial-of-service, not escape. A process constrained by cgroups still makes syscalls to the same kernel with the same attack surface.
