| The answer, in summary:
|  * Use select.select() to wait for input.  Provide the list
|    [sys.stdin, mysocket] to select.  This is Unix-specific.
|  * When select tells you that there's input waiting on stdin,
|    use os.read(sys.stdin.fileno(), 1000) to get it.

For a little more UNIX trivia:  sys.stdin.fileno() is always 0,
by definition.  Likewise, sys.stdout.fileno() is 1, and stderr 2.
The file object is only a superfluous inconvenience.
