That is progress on KS, not Lucy.

It's not that you aren't doing good stuff Marvin.  You are.  I love  
your discussions on Lucene Java and you are no doubt doing interesting  
stuff on KS.  It's just that, as Jukka, has pointed out, Lucy has seen  
absolutely zero of this effort for over three years.  How long do we  
hang on to your promise?  And, it is only you doing so.  That is not a  
community and not a definition of an Apache project.  It's fine for KS  
b/c that doesn't live in Apache.  It's not fine for Lucy, IMO.   
Sorry.  Heck, you and Nathan having a two person discussion on Lucy- 
dev on a regular basis would be enough to satisfy this.
