There are prebuilt slab allocators that do this well. I used the arena allocator in facebook's libfolly recently as the base for a huge page allocator, and the code turned out quite nice. I think the allocator is a much better abstraction here. You could use something like the arena allocator here to carve out the memory for all the vertex and mesh storage and amortize the cost of hundreds of objects as well, so I don't like the argument in the first few sentences of the article actually that allocators would take more space.
