I would have loved to see some data that showed their bump pointer regions and thread local stuff performing significantly better than tcmalloc or jemalloc, both of which do thread-local caching that avoids locks for the vast majority of allocations. Additionally, what they came up with sounds like talloc[1], which has been in production for years with samba.
