It has at least one potential use. On Windows socket.detach() returns a socket handle but there is no documented way to close it -- os.close() will not work. The only way to close it that I can see (without resorting to ctypes) is with something like

socket.socket(fileno=handle).close()

There is an alternative (documented) interface: socket.fromfd(handle, socket.AF_INET, socket.SOCK_STREAM).close() ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue16802> _______________________________________
