The implementation is fully backwards-compatible for listeners that
are unaware of the new API. If the next() method is not called, then
all subsequent changes are delivered as usual by repeated listener
invocations.

If a listener only fetches some changes of a bulk operation (but stops
halfway through the operation), the remaining changes will also be
delivered with repeated listener invocations.


1. should this be included in javadoc?
2. could we add a test for this scenario?
