@AlanBateman 
I validated the `jdk/java/net/Socket/asyncClose/Race.java` with the [preClose.patch](https://github.com/user-attachments/files/20789395/preClose.patch) and ran it for 100 iterations, all of which passed successfully. Without the fix, it is failing at 22nd iteration.


TEST RESULT: Error. Program `/home/jenkins/shruthi/headstream_fix/without_fix/jdk/build/aix-ppc64-server-fastdebug/jdk/bin/java' timed out (timeout set to 120000ms, elapsed time including timeout handling was 122319ms).
