My understanding as well is that this is the purpose of #become:, but also that it is not very efficient in some versions of Smalltalk. If you are using an OrderedCollection, this is probably a reasonably efficient method as it doesn't need to search through the whole list every time it removes an element:
removeAll [self notEmpty] whileTrue: [self removeLast]

My own testing suggests that references to the object remain in place. I would guess that that is the whole point of become.

butI'd interested to see if it's a good use of #become:... Does it keep references ? is it safe ?
