My IRC bot that would run code for people taught me a lot about
sandboxing Lua, as well as the lengths people will go to to break bots
:P
You will inevitably run into problems everywhere unless you thread it
(LuaTask is a good choice). Simple things like table.concat or
string.find can eat cpu cycles indefinitely if they are smart.
Naturally debug library doesn't help you much if everything happens on
the C side of Lua.
HTH,
