You mean a limit to the time a script runs before it is cancelled? I
don't think that is possible right now in LuaJIT. LuaJIT emits pure
asm code, and if that code is in a loop, it just runs the loop as long
as it likes.

I am thinking about a process to patch arbitrary Lua code in order to
have it check a time limit at well-defined intervals (even when run in
LuaJIT). But that takes some work.

So probably all you can do right now is kill the whole thread/process
from outside.

I'm not even sure if I get your question though. What's luaV_execute?
