My understanding is that when you close the workspace, any instances  
you have created will become "unreferenced" and will therefore be GC'ed  
at some point. Meaning, anything you create within a workspace is local  
to that workspace only and will be "destroyed" after the workspace is  
no longer available. You can find a hint about this in  
http://www.iam.unibe.ch/~ducasse/FreeBooks/GuzdialBookDrafts/ 
TourSqueak-Ch2.pdf, page 5.
