It *might* look in /etc/hosts first, depending on what's in
/etc/nsswitch.conf.  At least with glibc anyway, other libc
implementations might do something different again.  Anyway it's far
enough into "it depends" that it's not something I'd want to rely on,
and as it stands it looks like we don't need to.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
