These however do guarantee internal state so any kind of new bug is much easier
to find and fix. Openswan does the same thing for this very reason. However,
openswan does have an init script that runs a while(1) loop over its daemon.
This means once we encounter unexpected state, we drop all state and restart.

Perhaps bind and/or distributions should also use such an init script. I would prefer
that over attempting to continue with a bad internal state and seeing apparent
random state/crashers later on in bind because it tried to continue after something
