Small correction: merging is never blocked because of open NRT
readers.  The merging happens and finishes even if you have NRT
readers opened.

It's the deletion of the ghost (merged away) segments that can't
happen until all open readers against those segments have been closed
(and until no commit point references these segments anymore).
