Hmm, it turns out I may have been a bit too hasty in blaming the newtls code
perhaps. We're running tests on resolver calls on the old setup vs. the new
one, and the behaviour is the same on on our pre-trunk (standard) config. We
may have just hit some threshold where it has suddenly started to matter, I
Anyway, I suppose the real lesson is the non-caching of gethostbyname calls.
Not being a DNS guru, I had no idea calls weren't cached locally. Let that
be a lesson, I guess.
