Just as a BTW for the squid list; the problem has been found. There were
stale /usr/lib/ binaries on the system. FreeBSD hasn't
shipped libresolv.* for a while (except for a runtime stub in /usr/lib/
compat/), so the gethostbyname() was using a version of res_send() that
didn't understand large file descriptors in select(), and I think it was
getting upset over changes to the layout of the _res structure that was
used in both libc and libresolv.

If there's any chance of getting libresolv specifically ignored for FreeBSD
as is libmalloc, it would save some torn out hair.
