This looks to be specific to ppc64, and I don't think I can help there much. I don't see an upstream bug about this. Could you start by getting a git checkout of CPython (https://github.com/python/cpython/) and trying to run tests there? Roughly: ./configure -C make -j$(nproc) make test If you could try 3.9 branch and master that would be helpful too.

I was hoping I'd be able to help you but I can't reproduce on the Gentoo ppc64 build host. Could you also try the top of '3.9' branch? You should be able to run that one test via: ./python ./Tools/scripts/run_tests.py test_subprocess (also would be nice to confirm that it happens when running it alone via that command)
single test still fails on 'v3.9.1' but it passes on '3.9' (895591c1f0): [...] Using random seed 982950 0:00:00 load avg: 0.51 Run tests in parallel using 34 child processes 0:00:30 load avg: 0.57 running: test_subprocess (30.0 sec) 0:00:51 load avg: 0.65 [1/1] test_subprocess passed (51.8 sec) /root/build/cpython/Lib/subprocess.py:1052: ResourceWarning: subprocess 407282 is still running _warn("subprocess %s is still running" % self.pid, ResourceWarning: Enable tracemalloc to get the object allocation traceback == Tests result: SUCCESS == 1 test OK.

Well, in that case we can either wait for the next upstream release, or you could try using 'git bisect' to find out which commit fixed it.

Obsolete, as python-3.9.2 has been stabled (bug #770853).
