      Description

      The forced eviction statistics in __wt_page_release_evict() are misleading: they assume that if a page's footprint wasn't large enough to force eviction, eviction was forced because of excess deleted items on a page. That's incorrect now that WT-4869 changed forced eviction to happen simply because the cache is struggling. (I doubt it was true before that change, too, but it's clearly not true now).
