I see 31mb image size for Pharo3 and 49mb for Pharo6. The changes file is about
the same. From the top command on a test system. "pharo" is a Pharo6 VM and
image and pharo-vm is the pharo3 system.

I looked a bit at memory usage and see if some random changes make a difference
* Shrink ZnMimeType ExtensionMaps to a minimum when not handling extensions?
* ASTCache reset to get rid of the spotter cache. Not sure if the
SessionManager runs ASTCache>>#shutDown properly. It looks like it should but
it doesn't?
* ByteString compaction? I did strs := ByteString allInstances. str -> strs
asSet. The numbers on a not fully clean image are 99874 vs. 42139. I wonder in
which hell I end if I use >>#becomeForward: to compact it (I tried this once
for GNU Smalltalk and I am sure others tried it before). I think anyone using
== on String is using the wrong class? Any good arguments against doing it?
I am moving my Pharo6 image into production right now and then will look into
setting up CI for Pharo7 with a minimal image.
