I have committed a kernel fix for this issue. It is not yet integrated into
the netbsd-5 branch but will be part of the final release.
pdnsd could fail in a different way because its socket calls will now error
out with EPIPE when the descriptor is closed, although that is not a bug in
NetBSD. I haven't looked at the pdnsd source so I can't say.
