Anyone know of a way to get non-blocking keyboard input?

I think this ought to work for some platforms:
try:
istty = sys.stdin.isatty()
except AttributeError:
istty = 0
if istty:
if os.name=='posix':
import tty
tty.setraw(sys.stdin.fileno())
elif os.name=='nt':
import win32file, win32con
hstdin = win32file._get_osfhandle(sys.stdin.fileno())
modes = (win32file.GetConsoleMode(hstdin)
& ~(win32con.ENABLE_LINE_INPUT
|win32con.ENABLE_ECHO_INPUT))
win32file.SetConsoleMode(hstdin, modes)
Unfortunately, GetConsoleMode, SetConsoleMode, and associated
constants don't seem to be included in win32all yet!
