All of this reminds me of an article by Dave Thomas in a magazine like
JOOP maybe eight years ago. In it he predicted that software systems
built using relatively small and simple virtual machines would be more
and more practical as the entire VM fit in cache along with enough of
the application and data.

Well the newer Pentiums this year will have what? Two megabytes of
level two cache?

What does the Apple Mac G3 have?
