Re: luabind and LuaJIT

Thanks for the information.  In the short term I've decided to disable
exception handling in luabind and modify the code so that in the case of
errors, luabind continues without calling std::terminate.  I understand why
the code terminates when exception handling is disabled (continuing is
certainly a bit dicey), but it might be nice option to have in the library
in general.
