      The Jenkins sanitizer stress tester hit an assertion:

      nice ./t
      [1449563601:673325][114594:0x7f0f327fe700], t, file:wt, sweep-server: ../src/conn/conn_dhandle.c, 608: dhandle != conn->cache->evict_file_next
      [1449563601:673410][114594:0x7f0f327fe700], t, file:wt, sweep-server: aborting WiredTiger library
