No, Lua uses a precise non-moving incremental mark-and-sweep
collector. It does not move memory around, which would be a bad thing
for a language designed to be embedded in C.
But good for cpu which have many levels of cache system.
Copy many blocks of data in memory will refresh cache in each core of cpus.
Copy is bad for cache.This is why java is slow.
