+SETUP_TEARDOWN_TESTCONTEXT
+
+//  Issue 566 describes a problem in libzmq v4.0.0 where a dealer to router
+//  connection would fail randomly. The test works when the two sockets are
+//  on the same context, and failed when they were on separate contexts.
+//  Fixed by https://github.com/zeromq/libzmq/commit/be25cf.
