I don't have a problem, just would like to note that this was brought up at
NIST's workshop where all the nameservers were on the same switch.  Maybe
also there should be a note about that the shorter the TTL, the more often
it will be purged from caches, resulting in requries and re-validations.
For zone data that may be relatively static, that results in wasted
computations.  Something zone admins should keep in mind.
