> In method checkBlocks(), TestBlockReplacement 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.
