[feature request] backport lua 5.4 generational GC #141

Open suikabreaker opened 2 years ago

ATT.

I'm developing using OpenResty and have put heavy logic on lua(with relatively large in-memory data and lot of string manipulation, and a lot of functions), and I noticed that those permanent GC object also slows down GC.

If we can mannually specify object as permanent it may also be sufficient for my case.

here is an example of backporting: https://github.com/dibyendumajumdar/ravi/issues/196

and another example(for manully disable GC for specified object): https://yuerer.com/Lua-GC%E5%9E%83%E5%9C%BE%E5%9B%9E%E6%94%B6%E4%BC%98%E5%8C%96%E6%96%B9%E6%A1%88/
