Issue 4405 in pharo: PharoKernel generation

Status: FixProposed
Owner: pavel.krivanek

New issue 4405 by pavel.krivanek: PharoKernel generation
http://code.google.com/p/pharo/issues/detail?id=4405

This patch adds to the SmalltalkImage method categories PharoKernel and  
PharoKernel-private. It enables to generate PharoKernel directly from the  
Core image without need of external scripts.

Smalltalk shrinkToKernel

Currently it doesn't condense changes (bacause of hanging of CompiledMethod  
cleanUp when used direclty during the shrinking process).

Shrinking process setup changed.

CompiledMethod cleanUp doesn't hang. It only takes so much time :-)

I see. It does on CogVM, on standard SqueakVM shrinking works

Well, Marcus, the problem lies in the condensing of changes file. So we may  
start with this version that does the shrinking and saves the image but it  
doesn't condense the changes file. It works on SqueakVM and Cog.

The condensing of changes file works too but it requires starting the image  
again with a script containing:

Smalltalk condenseChanges.
Smalltalk saveImageInNewContext.
