Hi Daniel,

just looked at your changes you made on the whiteboard. You moved the 
"callback interface" idea to "Other Changes". I think that such an 
implementation would raise a change in the current api. Maybe we can 
make the new code backward compatible, but at least, we have to add 
additional methods where a callback object can be passed into classes 
like IndexWriter e.g.

The "logger" idea could be a candidate for "Other Changes". The only 
thing we would have to do is to add a seperate logger class which can be 
adressed from the internal lucene classes, which wouldn't have any 
changes within the api.

best regards
bernhard

>- 3. Implement a callback interface for processes which can run for several minutes like IndexWriter.optimize(). The idea is to define a simple public interface which can be implemented by developers using lucene. The object implementing the callback, could be passed to methods like optimize() and can inform the caller when one of the steps to process has finished. This would make it much easier in interactive applications to inform the user that the system is working and not frozen.
