That's not the point.  If you do a steady click-click-click on the
applet, that should not trigger a new scan each click.  At best, you'd
click, NM would scan, and if you clicked again within 5 or 10 seconds
you're out of luck.

So you'll never be able to get instantaneous scans _every_ time you
click on the applet, because that's a denial of service.
