That's exactly the case. And there is also the problem that I need to close
the sockets before calling zmq_term. I actually tried this solution (TLS)
but it started to look like a code smell, so I revisited the muti-thread
use of sockets.

As a side note, the guide really did a good job keeping me away from using
sockets from multiple threads :)

Thanks,
Thiago
