We used to set a no-reconcile flag when we open a history store cursor. This flag would have prevented a history store page from being force evicted just after doing a history store operation. We stopped setting that flag as part of history store cursor open in WT-5977. We would like to know how many history store pages are being evicted while history store cursor stays open, the pages we would not have evicted earlier. This statistic could help us catch eviction problems in the future.
