I can't remove portability concerns out of my mind (probably because I'm
currently working on console games), and afaik Coco is not supported on
current game consoles.

But I think I'll give it a try on x64 PC.

Thanks for the link. I also just discovered the Resumable VM patch [1].

This leads me to another question, to the authors (I hope they're
reading that thread). As stated in a previous list message [2], is that
patch still considered for inclusion in 5.2 ? Just by itself I think it
would be a good reason to release a 5.2. It's been around for a while
(in fact I just discovered it because it was presented/discussed on the
list prior to my adoption of Lua), so maybe some users could give some
feedback to help decide if it would be a worth evolution for Lua.
