              Message: WT-2249 Keep eviction stuck until cache usage is under 100%.

              Fix a real bug: STUCK is a cache flag, not a cache->state flag.

              Don't try to do eviction when dumping the cache, and only kill processes if no
              pages have been evicted since the STUCK flag was first set.
