But it's ok. [Smalltalk cleanUp: false] just releases cached objects. 
Some of these objects are released when the packages are unloaded, others 
are cleaned by SmalltalkImage >> #unloadAllKnownPackages, like:
 	Undeclared removeUnreferencedKeys.
 	StandardScriptingSystem initialize.
 	MCFileBasedRepository flushAllCaches.
 	MCDefinition clearInstances.
 	Behavior flushObsoleteSubclasses.
 	ChangeSet current clear.
etc.
