So, the userdata is being finalized after the module, right? Either it
was created after the module, and then we have a bug in Lua (that should
finalize it before the module), or it was created before the module, and
then we have a weird program (where a userdata needs in its finalizer a
function from a module that was not loaded yet). Can you tell what is
your case?
