-------------------------------------
> I think closing the old reader is fine. What do others think? Is keeping the

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.

> probably be folded into the core, if this looks good).
