      Description

      https://evergreen.mongodb.com/task/performance_linux_wt_repl_singleThreaded_a7338c436160e259d0b20058f0a9ae4b442ca102_15_08_28_06_06_32

      This is the same issue as SERVER-19445 – if the oldest transaction ID tracked by WiredTiger falls behind, workloads that do many updates to medium-large documents to hit forced eviction. The regression was introduced by WT-2066.
