Although Kohei already proposed an alternative, I'd like ask you
something. In you initial mail, you've stated "it turns out that we need
much more time updating the progress bar than we need to move the
sheet". How much is needed for such stuff - also considering rare cases?
If we could guarantee that moving stuff around will never take more than
(let's say) 1 second (complex document, old computer), then there is no
need to visualize the status of this operation. If not, then the user
has to be informed about that ... thus, Kohei's suggestion (as far as I
understand it (I'm not a developer) sounds very reasonable.
