The "unbound-control" man page describes this as slow, and "ic.ac.uk" is 
a big zone, soon to get a lot bigger when we DNSSEC sign it.

I'd prefer not to blow away more of the cache than I have to. As I say, 
most updates are 1/2 hosts in which case I guess reconnecting to the 
control channel is not too onerous, but it seems... icky.
