Great stuff, Nathan.

I'd like to move the design discussion to the Lucy developers list, so  
I'm going to direct my main reply there.  The ultimate home for the  
work that's gone into KinoSearch is probably going to be Apache.  I  
can put whatever I want into the rectangular.com KinoSearch subversion  
repository regardless, but stuff that goes into Lucy has to have been  
discussed in Apache channels.  So -- there's no drawback for KS if we  
have our conversation at Apache, but there's a benefit for Lucy.

What these benchmarks have shown is that the present implementation of  
"Flexible Indexing" in KinoSearch just isn't fast enough at search- 
time.  Change of some kind is required.  PForDelta merits serious  
consideration, but it's a substantial break from the current design.
