Hojun-Cho fa33357821 examples: lisp — chunked bump arena for value/env cells
Replaces rt_alloc-per-cell (one 4 KiB mmap each) with arena_alloc
over 64 KiB chunks. test_huge peak under massif --pages-as-heap=yes
drops from ~525 MB to ~253 MB. Same lifetime semantics; remaining
bulk is per-call append() in eval's arg slice (rt_ensure still
mmaps page-per-call).
