Test not-yet-reduced for bug 142994: Dynamic "newsticker" [DHTML scrolling message, javascript marquee] causes high CPU usage

The most helpful thing
you can do is
pull the pages apart
to determine the minimal code
required to spike the cpu
and then report them
as separate bugs
if they do not already
match known bugs.
Hovering the mouse cursor
over this text
will stop the marquee.
