X-Git-Tag: v3.13.0b4~40
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6396c77571aee99386a7b5a5863bbe0b8c5df4b1;p=thirdparty%2FPython%2Fcpython.git

[3.13] gh-117657: Skip tests that fork with threads under TSan (GH-121599) (#121819)

This avoids messages like:

  ThreadSanitizer: starting new threads after multi-threaded fork is not
  supported. Dying (set die_after_fork=0 to override)
(cherry picked from commit 82a4dac9f6131954c32dac9d0277283fc5b499a9)
