Great to see another lua based service. I'm running http://geolua.com/ http://geolua.com/ which also uses Python (and even gunicorn) for the web interface and lua (in a custom libevent based server) for running user provided lua code. I sandboxed lua using chroot, a custom allocator function, runtime limits using signals and an "outer" lua environment which interfaces with the python code. The inner environment should be safe. I guess :-) How do you handle 'a = " "; while true do a = a .. a end'? Do you spawn individual processes with process limits? Which version of lua are you using? Why not luajit2?
