> Right now isCurrent() will always return true for an NRT reader and getVersion() will
always return the version of the last commit.  This is because the NRT reader holds the live
segmentInfos.
> I think isCurrent() should return "false" when any further changes have occurred with
the writer, else true.   This is actually fairly easy to determine, since the writer tracks
how many docs & deletions are buffered in RAM and these counters only increase with each
change.
> getVersion should return the version as of when the reader was created.
