Hmm. Do you think we should skip these tests altogether, because they are not valid in the unix case? The alternative would be marking them pending, which I think might better communicate that we would like them to work but haven't gotten them there yet (that way it shows up in the test run instead of being silent/invisible). Make sense? You can mark pending by adding a line inside the test like `pending if connection.data[:scheme] == 'unix'`. Might be good to use the constant there, in any event, like `Excon::UNIX` or whatever. Not that I expect it to change, but just keeps things more consistent with the code base and reduces duplication.
