The AIX bot's are also in the red zone with PR17010.

This was examined earlier See: https://bugs.python.org/issue35633#msg333662

In short, the recommendation by Victor was to skip the test: quote:
> On AIX the test for flock() passes, but the test for lockf() fails: (...)

I would prefer to simply skip the lockf() test rather than ignoring PermissionError for flock() and lockf() on all platforms. 

And so,  Lib/test/eintrdata/eintr_tester.py now has:

    @unittest.skipIf(platform.system() == "AIX", "AIX returns PermissionError")
    def test_lockf(self):
        self._lock(fcntl.lockf, "lockf")


Thanks for your understanding.
