      Description

      The cache stalled in a sanitizer run:

      http://build.wiredtiger.com:8080/job/wiredtiger-test-format-stress-sanitizer/25881/console

      This is interesting because it's a reasonably large cache (180MB), but all the space is pinned in an object open for exclusive access (verify? rebalance?), and that shouldn't happen.

      We didn't get a core dump, so the only path here is likely trying to reproduce it based on the CONFIG.
