I agree this continues to fix the problem seen with the recursive approach. I also agree it should fix the CentOS hang.

However, I do not see how this will address the actual failure that is reported in JBS for this issue:

Testing NATIVE_OVERFLOW
Testing stack guard page behaviour for other thread
run_native_overflow 1281626
Got SIGSEGV(2) at address: 0xffff8daf3fa0
Test PASSED. Got access violation accessing guard page at 7983
Test PASSED. Not initial thread
];
 stderr: []
 exitValue = 139

The JBS connections and timeline is very hard to follow, but I believe this failure was seen after the hardening fix had been applied.
