I tried this once, using LPSM, a persistent memory library. See
It did not work well with userdata though it did work with C functions,
at least in those times of fixed loading address. I guess this no longer
Also, it was before Lua 5.2, which now contains hash randomization that
changes memory layout across invocations. So, I guess nothing like LPSM
will work. But I'd love to be proven wrong on this.
