Eeek! Now I see the problem. This is a problem in the FloatMathPlugin
that is present in many of the current VMs, and that will affect
users who run the updated image with the older (existing) VM. Details
are on Mantis here:
  http://bugs.squeak.org/view.php?id=7592

and discussed on the list in this thread:
  http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-December/156124.html

The issue will not be present in future VM builds, but if definitely
affects the current installed base.

In my view, we should revert the FloatMathPlugin changes in
Kernel-ar.531 for the Squeak 4.2 release, then reapply them to
the update stream immediately after the release.

I believe that Matthew Fulmer indicated that this would be OK for
his Cobalt work (if I interpret his message correctly):
  http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-December/156139.html

Does anyone disagree with this? i.e. that the FloatMathPlugin fixes
in Kernel-ar.531 should be temporarily reverted, then reapplied
after the Squeak 4.2 image is released?
