If all that code has to be touched, perhaps it would be better to switch
to something more efficient?

It would be nice to use something like libevent but that particular
library doesn't seem to support the threading model used by Asterisk.
That's a bit sad actually, as it even comes with an async DNS library.

Having to support both epoll and kqueue by hand would not be very nice,
so perhaps sticking with poll is the only way.

This graph is a bit scary for poll() and select() though:
