      Description

      This looks similar to WT-3289, where thread creation fails and when exiting we end up calling thread join on tid 0.

      Config to reproduce using fault injection script:

      cmd=python ../test/suite/run.py -v 3 test_shared_cache02
          failcountbeg=6
          failcountend=6
          timeout=300
      

      Induced fault here:

      Induced fault in following backtrace:
