Re: 0.91 luabind::call_function - leak

Does starting garbage collection once after the whole iteration remove 
the excess memory, too? In that case the garbage collection was just not 
being invoked since Lua didn't mind the couple of MBs enough yet to 
bother collecting them.

Because a metatable with class-related information gets stored in the 
registry. That's normal. There's no way to unregister something.
