Yes, a remote konqueror can be quite noisy (CPU fan) on a Win98 laptop
with Cygwin XFree :(
But khtml repainting looks a bit smarter:
   d->timerId = startTimer( parsing ? 1000 : 0 );
Also using a paintBuffer helps a lot.
Personally (= I have no intention to change that), I even think khtml
does it too fast. But the KFM can repaint four times in a second (taken
the above ftp site). Can't hardly call that progressive rendering.
Also, feedback is given by the progressbar.
