Description
The “AMD64 Windows11 Refleaks 3.12” sometimes deadlocks with:
3:58:18 load avg: 0.07 running (1): test.test_concurrent_futures.test_deadlock (2 hour 34 min)
3:58:48 load avg: 0.05 running (1): test.test_concurrent_futures.test_deadlock (2 hour 35 min)
3:59:18 load avg: 0.03 running (1): test.test_concurrent_futures.test_deadlock (2 hour 35 min)
3:59:48 load avg: 0.02 running (1): test.test_concurrent_futures.test_deadlock (2 hour 36 min)
command timed out: 14400 seconds elapsed running [b'Tools\\buildbot\\test.bat', b'-p', b'x64', b'-j2', b'-R', b'3:3', b'-u-cpu', b'-j2', b'--timeout', b'12000'], attempting to kill

On some builds, a different test fails:
3:58:59 load avg: 0.03 running (1): test.test_multiprocessing_spawn.test_threads (1 hour 43 min)
3:59:29 load avg: 0.06 running (1): test.test_multiprocessing_spawn.test_threads (1 hour 44 min)
command timed out: 14400 seconds elapsed running [b'Tools\\buildbot\\test.bat', b'-p', b'x64', b'-j2', b'-R', b'3:3', b'-u-cpu', b'-j2', b'--timeout', b'12000'], attempting to kill
3:59:59 load avg: 0.04 running (1): test.test_multiprocessing_spawn.test_threads (1 hour 44 min)
program finished with exit code 1

I am able to reproduce locally, by running these two (or this and test_concurrent_futures.test_shutdown) in parallel. The deadlock occurs in test_crash_big_data.
