Don't forget that not all computers are fast especially as the user
may be doing something else that is grabbing a lot of the CPU at the
time. I prefer Richard's method of occasional progress bar updates.
Unless you are sure that the process will be extremely quick in all
circumstances, removing the progress bar may not be a good solution.
