Actually, from what my network traces show, the data downloaded is the same
for files without custom icons REGARDLESS of view.

and, in fact, if you look at my fs_usage samples, The Finder is going out to
the applications on the local drive for file information quite a bit. Which
means my much earlier guess was right.

However, in list view, fs_usage shows up to 4x the amount of file system
accesses as in column view, which means that there's simply a lot more going
on in list view.
