Solr uses those internals ... but I remember hearing a LOT about
concurrent flushing in the leadup to the Lucene/Solr 4.0 release, and
what a performance boost it was for indexing speed.

I would be REALLY surprised to learn that Solr does NOT use it ... but I
would guess (again, no idea) that it uses it simply by accepting Lucene
defaults, not an through an explicit choice.
