Summary 0007250: Object>>#doesNotUnderstand: incorrectly handles a resumed MessageNotUnderstood
Description The implementation of #doesNotUnderstand: in Object does not check whether the signalled MessageNotUnderstood has been resumed and return the resumed value. Instead it simply resends the message. As a result, this will loop forever:

" should evaulate to 'abc' "
[Object new foo]
  on: MessageNotUnderstood
  do: [:e | e resume: 'abc']


This may be an issue in versions earlier than 3.10.

I wrote the fix I posted in response to your post.  It is not identical 
to the VW code, but it is essentially the same solution.  The solution 
is pretty obvious, so I don't think there will be any issues.
