// Regression test for GH-784
// https://github.com/joyent/node/issues/784
//
// The test works by making a total of 8 requests to the server. The first
// two are made with the server off - they should come back as ECONNREFUSED.
// The next two are made with server on - they should come back successful.
// The next two are made with the server off - and so on. Without the fix
// we were experiencing parse errors and instead of ECONNREFUSED.
