Right, it did not for your case. But that's because of the super short 
loop and the time_based setup, otherwise it would have. That was 
apparent while it was running too (not reads or V status), and in the 
final output (no reads there either). So it was a corner case where 
verify did not happen, since the referenced commit that broke it for 
that case.
