The flickering effect that you see otherwise is actually from the screen
repainting itself to redraw the cursor when these rapid changes of state
occur. Setting up an IBO "busy" loop stops the cursor from responding each
time a new fetch begins and so prevents the screen repaints. It's less
irritating for the user but, better still, it speeds things up, because
hundreds or thousands of rapid screen repaints are very demanding on the
client system's resources.
