dc5c8006f6 was recently merged to prefetch
up to 128 deadlists. Unfortunately, a loop was missing an increment,
such that it will prefetch all deadlists. The performance properties of
that patch probably should be re-evaluated.
This was caught by CodeQL's cpp/constant-comparison check in an
experimental branch where I am testing the security-and-extended
queries. It complained about the `i < 128` part of the loop condition
always evaluating to the same thing. The standard CodeQL configuration
we use missed this because it does not include that check.
