Problem: the function zproxy seems to have some issues

[monotone]

I use zproxy for a router frontend and a dealer backend which with a dealer worker connect to it.
And, there is two peers which are A and B connected to the router frontend. One is sending message forever, and another is receiving message forever. Then, the worker does receive from A and transmit the message to B.
Sometimes, the send operation of the worker is block, and lead to the A and B block too.
When i use zmq_proxy replace the function of zproxy, this situation is ok.

What`s the reason?
