Could you share a recipe for generating slightly higher loads?
Like, a few thousand concurrent connections, 10 calls per connection?
I just couldn't make httperf generate any sort of sensibly high load.

Ok, I missed that. Its required for event.h on some platforms though,
probably why I missed it.

That would also be my goal but I think the current patchset is a good
first step. I'd definitely like to get some more experience with the
libevent DNS and timer code so I'd like to look at doing that once this
curent work is committed and stable.
Thanks for reviewing it!
