The delay persists.

I tried with only google's 8.8.8.8 DNS server, same thing. I think this
could be something else.

The delay happens after the Nav_open_url https://geo.craigslist.org
line. I noticed that with the links terminal browser, the DNS activity
is four pairs of A and AAAA queries:

-- dns with links --
06:36 : query[A] craigslist.org from 10.0.0.1
06:36 : query[AAAA] craigslist.org from 10.0.0.1

06:36 : query[A] www.craigslist.org from 10.0.0.1
06:36 : query[AAAA] www.craigslist.org from 10.0.0.1

06:36 : query[A] geo.craigslist.org from 10.0.0.1
06:36 : query[AAAA] geo.craigslist.org from 10.0.0.1

06:36 : query[A] montreal.craigslist.ca from 10.0.0.1
06:36 : query[AAAA] montreal.craigslist.ca from 10.0.0.1
--

While dillo has an extra www.craigslist.org query, and none of the last
three have a corresponding AAAA query:

-- dns with dillo
06:46 : query[A] craigslist.org from 10.0.0.1
06:46 : query[AAAA] craigslist.org from 10.0.0.1

06:47 : query[A] www.craigslist.org from 10.0.0.1
06:47 : query[AAAA] www.craigslist.org from 10.0.0.1

06:47 : query[A] www.craigslist.org from 10.0.0.1

06:47 : query[A] geo.craigslist.org from 10.0.0.1

08:18 : query[A] montreal.craigslist.ca from 10.0.0.1
