Antoine Pitrou e1dd1747e8 Issue #8411: new condition variable emulation under Windows for the new GIL,
by Kristján.  Unfortunately the 3.x Windows buildbots are in a wreck, so we'll
have to watch them when they become fit again.

Jeffrey Yasskin 39370830a9 Make (most of) Python's tests pass under Thread Sanitizer.
http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data
race detector that runs on top of valgrind. With this patch, the binaries at
http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many
but not all of the Python tests. All of regrtest still passes outside of tsan.

I've implemented part of the C1x atomic types so that we can explicitly mark
variables that are used across threads, and get defined behavior as compilers
advance.

I've added tsan's client header and implementation to the codebase in
dynamic_annotations.{h,c} (docs at
http://code.google.com/p/data-race-test/wiki/DynamicAnnotations).
Unfortunately, I haven't been able to get helgrind and drd to give sensible
error messages, even when I use their client annotations, so I'm not supporting
them.

Antoine Pitrou a1d23326b1 Try to strengthen condition-waiting under Windows.
If it doesn't work (doesn't solve erratic freezes) we'll have to resort
to tougher (Windows-only) measures.

Antoine Pitrou cf4cabbe2a Our condition variable emulation under Windows is imperfect, which
seems to be the cause of the buildbot hangs. Try to fix it, and add
some comments.
