From the excellent blog  http://playingwithobjects.wordpress.com/  Guille was doing we read

The results of the project so far are:

• It can create an Smalltalk image living inside another image.
• This inner/guest image can be written in a new .image file.
• With this approach a small kernel of 1.1MB has been reached.
• SpaceTally runs and prints reports to understand how the space is distributed among objects.
• A tool to detect every uninitialized class variable/class instance variable and references to unexistant globals was developed.
  

I like to know exact steps for doing this, so maybe can feedback some..
