      Description

      test/format presumably hung because it aborted after 15 minutes. The cache dump shows that the cache is not close to full which implies a hang or deadlock. This was running a sanitizer job on tinderbox. The job is at http://build.wiredtiger.com:8080/job/wiredtiger-test-race-condition-stress-sanitizer/32901/

      This one is different than WT-4653 because this does not involve LSM. It is a variable-length column store.
