If you're into alternative Lua distributions, LuaPlus's LuaObject
(http://wwhiz.com/LuaPlus/index.html) almost completely eliminates Lua stack
management under C++.  In addition to that basic functionality, it
implements a solution similar to the one described in the above thread and
autoexpands the stack as needed.

If you're not into non-mainstream Lua distributions, you'll just have to
follow the lua_checkstack() approach above.
