> For apps using a large index and frequently need to commit and resolve deletes, the cost
of opening the SegmentReaders on demand for every commit can be prohibitive.
> We an already pool readers (NRT does so), but, we only turn it on if NRT readers are
in use.
> We should allow separate control.
> We should do this after LUCENE-2294.
