This should work in principle (assuming the module itself doesn't do
anything wrong).
Each lua state maintains its own independent table of loaded modules, so
dlopen/LoadLibrary will be called twice; for both functions, this is
specifically allowed, and a reference count of the number of opens is
kept by the system so that the module isn't unmapped until it has been
closed as many times as it was loaded.
