Out of curiosity, what "undocumented assumptions" and games with GDTs
would you be talking about?  I don't think I play any games. I do some
clever things to cut down on the number of GDTs I grab (well they're
clever in my opinion :-) but I don't think I do anything "illegal".

Could you be a bit more specific?

Thanks...
