tlpretest question for luatex experts

[Karl Berry]

    There are four lua binaries: luahbtex, luajithbtex, luatex, luajittex. 
    LuaTeX experts, here are our questions:

            a) Should we claim the same exceptions for all four binaries?

Yes. All Lua variants are equally insecure in this regard.

            b) Are there short sample programs we can use to check that the
    binaries work correctly after the exceptions are applied?

I don't have any such test programs. Luigi? --best, karl.
