I am a old novice, know noting about comet
can anyone give me hint ?

As stated in select documentation (http://docs.python.org/library/
select.html?highlight=select#select.select), three empty sequences as
parameters for select does not work under windows.

I think at startup, as there is no client, self.clients is an empty
sequence, therefore it fails under windows. So at the moment chat demo
does not work under windows.

As I don't immediatly have access to a windows machine, can you try to
add the line `if not self.clients: return` before line #113 in
`comet.py`?
