Thank you for point this out.

In fact Smalltalk is the global variable which references
      SmalltalkImage current

So I can do as well

      SmalltalkImage current unloadAllKnownPackages


Which I did

Squeak4.2-10382-alpha.image went from 16998KB

down to
10277kB
(file sizes measured on Windows machine)

Yes, I tried it for the HelpSystem

I added three more entries to the literal array in the method

"Go unloading"
	#(	'ReleaseBuilder' 'ScriptLoader'
		'311Deprecated' '39Deprecated'
		'Universes' 'SMLoader' 'SMBase' 'Installer-Core'
		'VersionNumberTests' 'VersionNumber'
		'Services-Base' 'PreferenceBrowser' 'Nebraska'
		'ToolBuilder-MVC' 'ST80'
		'CollectionsTests' 'GraphicsTests' 'KernelTests'  'MorphicTests'
		'MultilingualTests' 'NetworkTests' 'ToolsTests' 'TraitsTests'
		'SystemChangeNotification-Tests' 'FlexibleVocabularies'
		'EToys' 'Protocols' 'XML-Parser' 'Tests' 'SUnitGUI',
'HelpSystem-Core', 'HelpSystem-Tests', 'HelpSystem-Project'
	) do:[:pkgName| (MCPackage named: pkgName) unload].


The image is now
10174kB (=100kB less10277kB).

Probably not worth the effort at this time.

Questions
1)  Which are the packages which are big and easy to unload.....?
2) Who does an attempt to unload the TrueType?
