Zach Brown 206c24c41f Retry stale item reads instead of stopping reclaim ...

Readers can read a set of items that is stale with respect to items that
were dirtied and written under a local cluster lock after the read
started.

The active reader machanism addressed this by refusing to shrink pages
that could contain items that were dirtied while any readers were in
flight.  Under the right circumstances this can result in refusing to
shrink quite a lot of pages indeed.

This changes the mechanism to allow pages to be reclaimed, and instead
forces stale readers to retry.  The gamble is that reads are much faster
than writes.  A small fraction should have to retry, and when they do
they can be satisfied by the block cache.
