Please back the TLS emulation patch out of 4.2, and queue it for 4.1. 
As others have said, this does not fix regressions, and should be queued 
for Stage 1.  I have every confidence that you can fix the AIX issues, 
and any other issues, but the window for new features has long since closed.

Thanks,
