gethostby*() and friends don't need thread safe back ends, because
they're not thread safe themselves, and do not need to be, according
to the relevant standards (SUSv2, SUSv3).

(Just because BIND8 decided to implement them as thread safe doesn't
mean that it's a requirement to do so.)

Which APIs need thread safety as per the relevant standards will
be affected by this?
