For allocated-in/owned-by-C++ objectsI use generally use _normal_
userdata + C++ reference counting:  the userdata holds a pointer to the
C++ obj.  

The userdata gets GCed as normal by Lua, and if Lua decides to delete
it, that ends up decrementing the C++ reference count, which may delete
the pointed-to C++ object (or not, if there are remaining references
from other C++ objects).

This works very well for me.  [Whereas light userdata never seems
particularly useful...]
