Ah sorry, I was incorrect about luaL_requiref.
I was didn't read the code correctly:
  - luaL_findtable is called from luaL_pushmodule
  - luaL_pushmodule is called from luaL_openlib
  - I confused luaL_openlib for luaL_openlibs (note the 's')
  - From which I saw luaL_requiref due to `ltests.h` (the lua test suite).
  - At which point I jumped to a conclusion that luaL_requiref was
using luaL_findtable to create tables.... Which is entirely incorrect.

Sorry for the noise.
