Excellent. I should really have discovered that.
reconfig also appears to be robust in the sense that configuration
syntax errors do not cause the daemon to exit.
I am a little apprehensive about having to prod BIND in case that
action compounds any problems, i.e. it would be embarrassing if the
very mechanism designed to gloss over a transient network problem
affecting one resolver were to clobber the remaining resolvers.
However, I hope that this will prove unfounded.
