Not clear on what this means; surely neither peer is connected if we fail? ;)

[Sergey Ulanov, 2011/12/12 22:52:00]

It is a counter for QuitThreadOnCounter(). I agree that the name is not correct
anymore. In any case, we don't need it anymore, I removed it.

I don't think this test belongs in a unit-test; it has no failure-mode except
(flaky) connection-setup, instead just printing timings, and by definition a
speed test needs to run for long enough to get reliable timings so it's too slow
for a unit test.
