- I did a stress test run on the jdk-23+14-1012 bits and the
       StressWrapper_MoCrazy_8H hangs reproduced on linux-x64:
       - linux-x64 with 1024 threads timed out:
         - release bits run-1 after 431 of 480 minutes
         - fastdebug bits run-1 after 444 of 480 minutes
         - slowdebug bits run-1 after 474 of 480 minutes

So this hang has nothing to do with the lightweight locking changes.
