Can you describe a use case where you want multiple threads to send/recv messages on the same socket?
The non-mutex/0MQ way to solve this problem (I think) is to
a) have each thread establish its own connection(s) into the ZMQ topology (i.e. don't share a connection!)
b) insert a mux/demux thread to coordinate everything:
+-- mux ---->
The mux thread is event driven and shuttles messages as needed.
What am I missing?
