Hm, update-cmm.192 purposely moved up ToolBuilder-Kernel-cmm.49 to
above Exceptions because it absorbs ProgressInitiationException, and
causes it to be "removed" from Exceptions (but still in the image,
which is critical to be able to continue the update).  At this point,
Exceptions is "changed" because of the removal of
ProgressInitiationException.

Then, update-cmm.193 simply moves it back down while also loading
Exceptions-cmm.35, which is the version without
ProgressInitiationException.

So, what I just did was to move Exceptions-cmm.35 to be loaded by
update-cmm.192, right after ToolBuilder-Kernel.  I don't know if this
will help, if not do you have any ideas?  (Update of my trunk image
worked, but I'm in the process of downloading a new alpha and trying
again).

Ok.
