Review Comment:
   I think that you could change the ExecutionStateSampler construction to take 
in some function to call when this timeout has happened. Then for unit test you 
could just pass in some lambda that notifies a completablefuture or 
countdownlatch and verify it is called.  In the real harness, you could pass in 
a function that call System.exit or otherwise ends up terminating the harness.
