So stack traces are masculine, I didn't know that.
I think your analysis is right, it's just that the sleep(10) is not
sufficient to ensure that the thread gets to the read method. Increasing
the sleep is probably sufficient. The hack to look at the stack trace
makes it more robust for really extreme cases, at the cost of potential
further maintenance in the event that the implementation changes. In any
case it's good to resolve this intermittent test failure.
