TestTimeout fails on mac about ice

[enobufs]

The cause.

The test is checking two things.

1. Timeout should not occur before the given timeout
2. Timeout should occur after the given timeout

The first one is failing.

The test checks the connection state every 100 msec. Each time it registers a task to retrieve the connection state after sleeping on the 100 msec timer. When it detect the state change, it compares cnt (time.Duration) assuming that is the current elapsed time, with the expected timeout duration. It is failing because cnt is 29.9 sec, But this cnt is the time before the 100ms-sleep. I confirmed that the actual time duration for the state change took:

transport_test.go:45: Elapsed: 30.002025 [sec]

Which is right after the expected timeout interval. So, how it tests is the problem.
