I took this idea, changed ldns-verify-zone and run some benchmark.

Tested with two zones with ~25000 delegations and one with ~350000
delegations, the -d option runs 20% faster.

On the small zones, takes less than 1 minute to run, but on the big zone
takes more than an hour, so is still unacceptable.

The patch is attached.
