What we really want is a general solution for the problem of how to
update class X safely when the update procedure uses class X.

Others have needed to do this more than once over the years, but it's
not easy. The answer is to create a new image file that has all the
objects you want, then run that. That is to say, in step two you'll
quit running whatever Squeak image you've been running and start
running the new one that you made in step one. In step one, you'll
make a new Squeak image file, and maybe the sources to go with it. See
what this page has to say about using SystemTracer, if you have to go
that route.

I don't know where you can get the original SystemTracer. You can find
SystemTracer2 on SqueakSource.

Good luck with it!
