…ack (pythonGH-155120) Add the @support.run_with_limited_c_stack() decorator which runs the test in a thread with a 8 MiB C stack, so that the outcome does not depend on RLIMIT_STACK. Use it in tests which recurse to a fixed depth -- @support.skip_if_huge_c_stack() failed to skip them with a 16 MiB stack. (cherry picked from commit ce5ae29) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com> Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
