Edgar, one reason I am slow to respond is that I am busy.  Another is
that I am not really a Squeak expert (though I am a Smalltalk expert)
and so I want to think about things a little.  But a very important
reason to be slow is that it gives more people time to comment, and
the more comments, the more we know.

You are right that it is time to release an image.  But I think it
should not be something that people get by updating from 3.9.   People
are too likely to get it by accident.  Moreover, not all changes can
be in the update stream.  Imagine the day we finally install
KernelImage and have Morphic all loadable from MC!  I don't think we
are going to be able to put that in the update stream.

This is an example of the valuable insight that we get by waiting.
This ought to be in the class comment.
