For my next trick...
<sigh> I started manually transferring the zone with named-xfer and saw
the problem. I had:
kcls.org IN CNAME rain.kcls.org.
in the kcls zone file. BIND disapproves of moves like this. Older
versions complain, but still work - apparently 4.9.3-P1 just chokes on it.
The moral is, if you know it's wrong, don't do it!
