Have you considered that your library might be used by a process with
multiple Lua states, which come and go dynamically in parallel

My advice is NOT to have any global state in a library. Instead, all
the state should be linked to the object that the require function
returns. Doing otherwise is a source of persistent problems,
especially in the scenario above.
