The i860, in particular, was simplified by putting the responsibility
for scheduling on the compiler, as the IA64 is supposed to do, and that
particular feature was one of its biggest problems.

It isn't irrational to believe that IA64 will have features that, at the
time the architecture was designed, looked like good ideas, but that as
the system is implemented turn out to:

        1. be hard to implement efficiently,
        2. be hard to generate code for, or
        3. cause complications elsewhere in the design.

I'm not making any claim that such problems exist. I'm simply saying
that there are ample historical precedents for clever and otherwise well
designed architectures to run into unexpected bottlenecks as the paper
turns into silicon.

They may exist. They may not. There may be unexpected complications elsewhere.
What we do know is that HP appears to be backing away from IA64 slightly as
the hardware approaches reality, and that approach seems inordinately delayed.
