[zeromq-dev] Upstream/Downstream simple example

other than zmq_sleep and zmq_stopwatch being missing in 2.0.7 i ran
into another problem
in receive_replies.cpp, line 65 should declare a variable sync
containing an empty message.

zmq::message_t sync;
out_socket.send (sync);

right now i think its sending the address of the sync syscall ?

with that fix, and using usleep() and gettimeofday() the example works
on my machine (fedora 13 x86_64)
