LGTM - mapping small TTLs to 30 would seem sensible.

I would suggest that we map all other positive numbers below, say, 30 to 30.

There is no reason for us to have a TTL less than that - we don't want to ever churn faster than that.

That was my original suggestion :)

Otherwise the local root monitoring thread will busy loop.
