I'm taking the image that's in the squeak-ci repository and updating
it. That's not _terribly_ old. Maybe a few weeks out of date. (I could
go check, but it's all the way in the other tab...)

The problem arises when loading Morphic-fbs.663 from update-fbs.239.
At this point you get a walkback because Kernel-fbs.791 isn't loaded.
This contains the bugfix that lets you load a class with a nil
Environment, but of course it also includes all the changes between
Kernel-fbs.779 and -791. By the time you've started loading
Morphic-fbs.663 it's too late to try load Kernel-fbs.791. But you also
can't just load Kernel-fbs.791 before you start the update, because
the image hangs doing _something_, presumably because the other stuff
in the diff between Kernel-fbs.779 Kernel-fbs.791 requires other
packages to be loaded.

So what's next? One hack might be to quietly reissue update-fbs.239,
but (a) that's disgusting and (b) I'd always understood config maps to
be immutable and (c) it sounds like a recipe for disaster.

I don't think I need an Environments expert, but I do need a
Monticello expert. Takers? Volunteers?
