I'm not arguing that Soft is immune, or that it does not have a problem, or 
that each application behaves exactly the same. We clearly see differences 
between apps, which in my opinion is due to the differences in what each 
application is trying to do during each refresh cycle OR how the developer 
insulates interface refresh from excess operations during the refresh cycle. 
And in the case of Softimage, I would expect it to be far more susceptible 
because of the underlying ICE evaluation structure. I saw similar issues with 
Maya, but most often saw it when we had expressions driving large numbers of 
objects in that software.

The problem is similar to the refresh issue in Windows explorer for directories 
that have large numbers of files.  Are the two conditions related? Not sure. 
The only point I was trying to make is that this phenomenon is not isolated 
strictly to Softimage and is potentially unavoidable due to factors beyond 
Softimage's control. Can it be mitigated? Absolutely. We've seen other 
developers implement unique tactics to mitigate the issue even while they can't 
remove it altogether. But there's usually always a trade-off in the mitigation 
as it's most often only a treatment and not a cure.

Could Softimage be modified to mitigate the problem? I have no doubt. The 
question though is what will it change or what will be the trade-off?

This may well me the case, but I can tell you with some certainty that in 
multi-thousand object scenes, Softimage handles simple operations like a total 
dog compared to some of its competitors. Especialy when there are tons of 
operators, Softimage can be absolutely painful to use.

I completely agree with this. However I would like to add that any lack of 
performance regarding high object count is probably less an issue with the 3D 
app  than an inherent processing limitation within most high end graphics 
systems.
