[zeromq-dev] Test test_pair_tcp.cpp hangs at bounce()

[Manuel Segura]

I tried to add socket monitors to check the handshake, but it hangs when
trying to read in an event from the monitor socket in the first call to
zmq_msg_recv(), specifically this line:

if (zmq_msg_recv (&msg, monitor, 0) == -1)

It appears to be the same problem with receiving when I called
bounce() from testutils.hpp, only this time its with the inproc protocol.
