[Stackless] Networking code

[Adam Bark]

Here's some pretty low level networking code I knocked up to encapsulate the
actual sending and recieving. It runs in the main thread along with
everything else so should be useful for anywhere without them or whatever. I
hope somebody else might find it useful considering the amount of talk on
here about networking. Oh yeah it's public domain I suppose, don't want
anybody stopping others using it or something :p

def recv_data(sock):
    print "receiving"
    sock.setblocking(0)
    poller = select.poll()
    poller.register(sock, select.POLLIN)
    while True:
        if poller.poll(0):
            return sock.recv(1024)
        stackless.schedule()

def send_data(sock, data):
    sock.setblocking(0)
    poller = select.poll()
    poller.register(sock, select.POLLOUT)
    while True:
        if poller.poll(0):
            sent = sock.send(data)
            if sent == len(data):
                break
            else:
                data = data[sent:]
        stackless.schedule()
