No it's not.
It says "Rather than play interesting games with vmas..", but:
- it doesn't say why the new model is any better
- and the source code *still* has to play all the same interestign games
anyway due to s390 (and possibly others) that cannot play the *new*
interesting games.
So I repeat: what's the _point_.

I don't think it can, since you have to leave the old code anyway.
Which just returns me to the original question: what's the actual
improvement here?
