> The test can fail due to random number collision, claiming there are
> unreferenced elements for obvious reasons (we rewrite some link). Original
> Accumulo test has one-stage generation so it doesn't count unreferenced
> elements as failures, only undefined ones. With 200m longs out of half-long
> range the probability of collision is approx 0.2%.
> Moreover, without some way to debug, it's hard to debug what keys should be
> looked at in such cases
