There is a simpler solution, but not that simpler. You can keep a
map from light userdata (the pointer to the userdata) to the
userdata themselves.

Nevertheless, this map still must be kept in a weak table if you want
Lua to colect the userdata. (But that seems dangerous if other parts of
your code keep a pointer to it.)
