Also, are you sure the things returned by socket.fleno() are really Windows handles? I thought they were some other artificial namespace used just by sockets. (You know what? I know understand and love the UNIX concept "everything is file"!) I don't know if a socket handle is similar to file handles or if they are specials. At least, GetHandleInformation() and SetHandleInformation() functions, used by os.get/sethandleinheritable(), accept socket handles.

Anti-virus software and firewalls can stop SetHandleInformation() from working properly on sockets:
