10 min seems pretty reasonable to me. Allows for a reasonably short
delay where someone didn't set up the DNS zone before the delegation,
but prevents the hammering of a server with a true lame delegation.
While in the case of a true bad delegation, I wouldn't mind the typical
48 hour TTL from the TLDs, It seems a bit punitive for the guy who just
forgot to do a restart of his server before changing delegation.
