[Twisted-Python] flushing the transport

[sir shz]

Hi, I'm just starting to write a simple client, whose protocol inherits from
basic.LineReceiver:

class MyClientProtocol(basic.LineReceiver):
     def connectionMade(self):
          stdout.write("\nconnectionMade\n")
          self.transport.write("test\r\n")
          # time.sleep(10)

now if I un-comment the "time.sleep(10)", the server doesn't receive the
"test\r\n" message until
10 seconds later, basically after the connectionMade() returns. Is there
anyway to "flush" the buffer so
the transport will send the "test\r\n" right away?

Thanks.

Z.
