The good news is that there's three ways to provide a satisfactory user
experience:  (1) Make the operation fast enough that it's effectively
instantaneous, (2) take as long as you like to complete the operation but
present user feedback (hourglass, non-determinate progress bar)
instantaneously, and (3) update the view instantaneously but complete the
operation asynchonously.
