This flag already exists and it's called "self.released_target_info" 
(check the end of the relase_target_info() method).
Then you want to use the KeyError exception path in File.changed() like 
this:

           if node is None:
             try:
                 return self._memo['changed']
             except KeyError:
                 if self.released_target_info:
                     # We have no executor anymore, but the cached "changed"
                     # value doesn't exist either -> print stacktrace!
