> I am watching a nightly benchmark run slowly run its {{CheckIndex}} step, 
> using a single core out of the 128 cores the box has.
> It seems like this is an embarrassingly parallel problem, if the index has 
> multiple segments, and would finish much more quickly on concurrent hardware 
> if we did "thread per segment".
> If wanted to get even further concurrency, each part of the Lucene index that 
> is checked is also independent, so it could be "thread per segment per part".
