[issue20431] Should posix functions that accept fd also accept objects with .fileno()?

[Larry Hastings]

Larry Hastings added the comment:

The functions that use PyObject_AsFileDescriptor() also call _PyVerify_fd(), which magically determines whether or not the file descriptor is valid.  Only works on Windows though.
