ReadAheadIterator

You've declared it to "implement Iterator<TestResult>" but I don't see 
any place where you
rely on it being a TestResult ... which is confirmed by the fact that 
you've had to newly-import
TestResult.

An arguably more abstract way of doing this would be to declare

   36 public class ReadAheadIterator<T> implements Iterator<T>

so that there is no unnecessary dependence on TestResult in this class.

The dependence on TestResult can then be expressed at the use site.
