In a multi-threaded environment, one wants to open a new reader, but needs to wait until all
requests finish before closing the old reader.  Seems like reference counting is the only
way to handle that case.

> This is Robert Engels' implementation of IndexReader.reopen() functionality, as a set
of 3 new classes (this was easier for him to implement, but should probably be folded into
the core, if this looks good).
