Ah I am sure you have told me that before, but I forgot and the man page
didn't remind me :-)
And I had falsely got the impression from RFC 1995 that IXFR-over-UDP was
the norm, but all the IXFRs in my logs are over TCP, and named/xfrout.c
* Sending a single SOA record is also how we refuse
* IXFR over UDP (currently, we always do).
Which suggests my guess about the cause of Mart's problem was wrong,
though I suppose it could still be a TCP MTU problem.
