Recently in Master, there was a several-day performance regression
that resulted in this behavior all the time on all of my ION
frontends.  While the progress bar was animating, nothing else
happened yet the CPU was at 100%.  My theme's base.xml has a section
like this:

        <imagetype name="animation">
            <area>415,340,33,33</area>
            <filepattern low="0"
high="11">images/widgets/busy/busy_%1.png</filepattern>
            <delay>100</delay>
        </imagetype>

Changing the "delay" element from 100 (milliseconds) to something
larger like 300 or 1000 fixed the problem.  Or more accurately, worked
around the problem.

This performance regression never hit the -fixes branch, but whatever
race condition was being hit is probably still lurking in 0.25-fixes
and Master, and may be affecting you.
