fjSrSSKrSSKrSSKrSSKr\R "SSS9 Sr\R"\"55 \R"5 \ "S5 \R"S5 g)aOut-of-process payload for the free-threaded switch/critical-section deadlock. See ``freethread_switch_deadlock.py`` in the repo root for the full write-up. Before the fix, a greenlet switch swapped C stacks but left any held ``PyCriticalSection`` locks (tracked in ``tstate->critical_section``) locked. asyncio's ``Task.__step`` holds such a lock on the running task across the step, so switching into a child greenlet and touching that task from there blocked forever. A fixed build (and any GIL-enabled build) prints the sentinel; a regressed free-threaded build deadlocks, and the watchdog turns that hang into a non-zero exit so the test fails loudly instead of stalling the whole suite.
