 It is imperative that the user manually synchronize on the
 map when iterating over any of its collection views:
 <pre>
  Set s = diff.modified2.keySet();  // Needn't be in synchronized block
      ...
  synchronized(diff) {  // Synchronizing on diff, not diff.modified2 or s!

 Failure to follow this advice may result in non-deterministic behavior.

 <p>The returned map will be serializable if the specified map is
