Actually, the original code didn't have the sock.setblocking(0), the 
problem I am trying to find is that the server does have 
sock.setblocking(0) (I can't change that) and it is getting the same 
error as my client has with the sock.setblocking(0), except it gets it 
on the accept() call. I tried modifying my code to be like this :

def sendMessage(host, port, msg):
   
    if isinstance(msg, unicode):
        msg = msg.encode("utf-8")
   
    burstSize = 4096
   
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock.connect((host, port))
    while msg:
        sent = sock.send(msg[:burstSize])
        print "Sending %d bytes..." % sent
        if sent == 0:
            raise RuntimeError, "socket connection broken"
        msg = msg[burstSize:]
    sock.close()

thinking maybe if I send small parts it would work better but this does 
not seem to change anything.
How are large msgs sent w/ a socket in python to a non-blocking server? 
The msg I'm trying to send is 175213 bytes long.

Thank,
