Execute the following...

	ChangeSet allInstancesDo: [:cs | cs zapHistory].
	(Smalltalk keys select: [:k | k beginsWith: 'AnObs'])
		do: [:key | Smalltalk removeKey: key].
	Smalltalk forgetDoIts.

[this should release the major causes for old classes being held onto]
and then print this...

Smalltalk obsoleteClasses

It should give an empty array.  If not, tell me what you get off line.
