This is not true.  java.util.Vector.Itr<E> does go through the same 
mutex as the Vector it is iterating.  But, as Jörg and others have 
noted, synchronizing all methods is not sufficient to ensure thread 
safety - especially not if multiple method calls must be executed 
atomically.  Then you still need an explicit synchronized block.
