Nathan, I would appreciate it if you would either quote text verbatim,

your edited quotes discombobulating. Thanks.

You might want to read this, which you might have missed the first time:

http://gcc.gnu.org/ml/libstdc++/2002-01/msg00125.html

If so, I strongly suggest that you start working on making the thread ABI 
forward-looking.

I'm surprised that you are so surprised about this.
