 > Can you give more info about the reasoning for the test case changes

 The old version of the tests didn't hit enough codepaths, since the
 protocol name was entirely unknown it would bail out early and never reach
 the part where it had to call .retain(). So now they test that it doesn't
 hang nearly forever.
