This test fails when run in a debian docker container from a OSX host with the following error:

test test_os failed -- Traceback (most recent call last):
  File "/build/Python-3.6.3/Lib/test/test_os.py", line 3273, in test_attributes
    self.check_entry(entry, 'dir', True, False, False)
  File "/build/Python-3.6.3/Lib/test/test_os.py", line 3228, in check_entry
    os.stat(entry.path, follow_symlinks=False).st_ino)
AssertionError: 3018467 != 1419357

works fine when run on ubuntu host.  If this is a docker problem I'd be happy to report there.
