The attached patch would (probably) do it, but then some poor developer
not on FreeBSD will spend hours later debugging why a bug (or non-use of
a cache etc) only happens for names including a _.

I know these are 'banned' in DNS, but I strongly object to the client OS
being the arbiter of good taste in network naming.
