Hi Shawn,

I guess if something prevents the current searcher from being recycled
(e.g. incrementing its ref count), it would be possible to re-use it for
the pagination - then the consumer could get tight to the reader and the
order is stable (seeing the same data) but there probably is not a
mechanism for this (?) nor would it be very wise to have such a mechanism
(?).
