Given that there's no way to break an infinite loop before 5.2 and that Lua will be used by people who experiment with scripts, I'd rather stick to 5.3 unless someone finds an acceptable workaround working with 5.2. I'd rather avoid seeing people report unresponsive haproxy just because of bugs in their Lua scripts :-/ Willy
