According to the discussion in PR 14051: if os.dup() fails to make the new file descriptor new inheritable for a character device, the error must not be ignored. Instead, the caller is supposed to use os.dup(fd, inheritable=False). Before this bugfix, os.dup() didn't respect its contract: fd2 was inheritable sometimes. Now the caller is aware of such special case and so can handle it properly.
