Hi, python-dev.
I'd propose removing code which I think out-of-date.
CPython has provided the own implementation for thread-local storage (TLS)
on Python/thread.c, it's used in the case which a platform has not supplied
native TLS. However, currently all supported platforms (NT and pthreads)
have

I'm in favor of removing it. I know that it confused people many
times, they look at this fallback and found an issue, whereas I'm not
aware of any platform using this fallback anymore.
Can you please write a PR just to remove this fallback? We can merge
it and then check buildbots :-) So in the w
Also note that C11, MSVC and some Unix C compilers have built-in support
for thread-local variables. Example:

Hi,
Sometimes, for an unknown reason, test_nntplib fails randomly:
http://bugs.python.org/issue19613
Martin Panter wrote a patch, but since I don't know how to reproduce
the bug, I'm unable to test it. Moreover, I don't know nntplib nor
test_nntplib, so I don't feel able to review it.
Sadly,

Handling fallbacks when shiny new features are unavailable is what
autoconf is for, though :)
The fact thread specific storage support made it directly into C11
makes me more confident in dropping our emulation,

Already done!

(and no buildbot complained).
