Yes, it gets real slow. It happens quite often when a long single line is
shown on the window currently, like in your amazon html example.

Try this instead,

pprint(urllib.urlopen('http://www.amazon.com').readlines())

It won't get slow even when it's still on the screen; it inserts multiple
(short) lines. If you have to insert a lot of long lines, maybe you have to
look into WCK and customize it as Michael said in his posting to the
thread. (I'm interested to see his "extremely fast" text widget, too)
