Well, that destructor must have been called from the collectgarbage
loop in the interpreter, so you can always store the passed state

Another simple stuff is to just stuff the pointer to the main state in
the registry, using a lightuserdata as a key. We do this with a couple
of functions, using the getter function address as a lightuserdata as
a key, and works like a charm.
