ZeroMQ PUB socket buffers all my out going data when it is connecting

Question

I noticed that a zeromq PUB socket will buffers all outgoing data if it is connecting, for example

import zmq
import time
context = zmq.Context()

# create a PUB

Here's a hack that might help...

Set your ZMQ::HWM to a fixed number, say 10. Upon connection, call the subscriber socket's recv method in a loop until it discards all the buffered messages, and only THEN start your main receiving loop.
