LOL.

The Mill guys took the arguments from the Itanium people, and turned
the crazy up to 11, with "the belt" and seemingly trying to do a
dataflow machine but not worrying over-much about memory accesses etc.

The whole "we'll deal with it in the compiler" is crazy talk.

In other words, I'll believe it when I see it. And I doubt we'll ever see it.
