Comment (by kean):

 As mentioned in #1772 there is no perfect solution for this other than
 scanning for an unused port. The real problem is, is that this particular
 port 47807 actually does have a common service running on it. So although
 not a perfect solution I am making a change to make this use port 56177
 which as far as my Googling indicates, isn't used by anyone at the moment.
 There are other ports used close to this one so essentially I just did a
 {{{s/4780/5617/g}}}.

 There is another problem with the tests and the workaround mentioned in
 #1772, and that is the use of ::1 in order to get around this problem.
 While it is true that having some IPv6, this will sadly make the tests
 fail if IPv6 isn't available or configured on the given platform. Using
 127.0.0.1 is definitely preferable and if we want to test IPv6 then we
 should have explicit IPv6 tests.
