Say, I set instruction count hook. If it is triggered (and some
condition is met -- given time passed, for example), I need to kill
Lua state. How do I kill it most gracefully? I'd like all allocated
resources to be freed. (I think it would be perfect to be able to
imitate conventional runtime error raised from the hook point. Not
sure if this is achievable though...)
I have an application that does this,
from inside the debug hook callback:
if (timeout) {
lua_pushstring(L, "Script timeout.");
lua_error(L);
}
and it *seems* to work fine, but I'm no expert...

another intresting question is how much will it affect the
performance?
