Nope. When handle_write() is called you are supposed to be *already* connected,
hence there's no point in calling connect() again.
This is clear if you look at handle_write_event method or read asyncore doc.

Nope. It means that *before* showing up the socket was *not* connected.

Of course it does: you're not connected yet (10057 = WSAENOTCONN).
You're supposed to use send() in handle_connect(), when the connection has
already been established.
This:
self.connect()
self.send('hello')
...is not asyncore is supposed to be used.
