[New-bugs-announce] [issue35633] test_eintr fails on AIX since fcntl functions were modified

New submission from Michael Felt <aixtools at felt.demon.nl>:

test_eintr fails on AIX since fcntl functions were modified
In issue35189 the fnctl() module was modified so that the EINTR interruption should be retried automatically.

On AIX the test for flock() passes, but the test for lockf() fails:

 ======================================================================
> ERROR: test_lockf (__main__.FNTLEINTRTest)

> PermissionError: [Errno 13] Permission denied
