Deconstructing the LuaJIT Pseudo Memory Leak

I only see Mike Pall's commits in https://github.com/openresty/luajit2/commits/v2.1-agentzh/ (agentzh's branch). So it looks Cloudflare has to pay for this mtrim patch.

This has to be AI slop text... It doesn't actually say what it does. If you've got a non-compacting GC that's fragmenting memory. If you need to release memory, then you better make sure that the blocks the GC is using are empty, and munmap them.
