Oh, duh. This was pretty silly.

This rule:

belies my (real Unix, where we use a -a on ifconfig, dernit)
heritage.

For whatever (inane, non-general, foolish, all imho, of course)
reason, Linux doesn't assign an index to the loopback interface.

(Sure, you almost definitely can't have more than one... you know,
unless you've got multiple backplanes with multiple processors on
each, which Sun will probably be doing about five years from now...
In any case network interfaces have a generalized form, dammit!)

Changing that rule to be:

iptables -A INPUT -i lo -p all -j ACCEPT 

Fixes the problem.
