AFAICS the exception is raised by the server side - and if I read it correctly it happens when the server finds that the socket is already closed when it tries to close it. How could sleeping between 2 process invocation solve this? The port used is an ephemeral port - so it should never be the same?

Hi Daniel,

I have also added some debugging info should this test fail in the future.

I've removed the proposed `Thread.sleep` and the test does not fail in 400 runs
