One question---does your allocator just assign the next available free

Lua freeing some garbage that isn't reflected in your custom allocator.

The placement algorithm is a little smarter than simply 'next free spot in an effort to reduce fragmentation. It maintains a free list of deallocated cells, so it does implement free() properly. Trust me, when it doesnt everything blows up very quickly with this little RAM! Im pretty sure of the allocators correctness, even though the fragmentation behaviour could probably be improved.
