    *** IMPORTANT NOTICE ***
    On Windows, only sockets are supported; on Unix, all file descriptors.



If under Unix, maybe sys.stdin.fileno() is a valid descriptor for
select. Just test it.

And if under Windows, you may take a look at
22.1 msvcrt - Useful routines from the MS VC++ runtime
22.1.2 Console I/O
kbhit( ) - Return true if a keypress is waiting to be read.
