Except the OS will close any network connections that are open, and if
you did your temporary file right, it will be ephemeral and will also
vanish on exit.

On older versions of Lua, you can of course just try to iterate _G and
destroy everything (except the os table) before calling os.exit() if
you're concerned.  (Bonus points for doing the same to the registry.)
