> In method checkBlocks(), TestBalancer waits forever on a condition. Failures
> result in Hudson/Jenkins "Timeout occurred" error message with no information
> about where or why. Need to replace with TimeoutException that throws a stack
> trace and useful info about the failure mode.
> Also investigate possible cause of failure.
