How about authoritative-only views?  I.e., if a query reaches
the bind instance but is in a view that does not have caching,
could it crash the instance? (I assume not.)

Also, folks who had problems: did anyone have a crash
by a bind instance that cannot receive queries from the outside
world?  I.e. incoming port 53 firewalled by the server or
an external device.

My assumption is that the crashes were typically triggered
by sites's own DNS queries, but it would be nice to
confirm that some site knows their crash happened that way.
