Currently the test randomly fails if you are using a shared machine due to contention on the well known port 1234. We can ameliorate this a bit by picking a random non-ephemeral port although it doesn't totally avoid the problem. While we could use a totally unique socket address for debugging it's impossible to probe for gdb support of the feature which makes this a sub-optimal but less fiddly option.
