Yes, but there are cases where this approach wouldn't help. Like, say, what 
happens when 20,000 files in a directory get removed. There, QIconView does 
pretty much the same removeRef(), only there is no easy way of special-casing 
that. (There are internal tools for doing stuff like that fast, BTW --- the 
widget can disable the updates and rebuild the containers all at once, but 
they're all private... )

Not yet, will do tommorow morning unless some hacker more experienced in 
dealing with TT does that before I wake up ;-)
