And NYTimes is not nearly the worst offender here.
No, browser vendors won't put in a two-second wait for each of these.
If we use the .5 of a second delay then there is 1 second of delay
total for this page attempting to connect through a broken IPv6
transport layer. .5 of second trying www.nytimes.com and .5 of a
second for each of the others however they are all being fetched
in parallel so the effective delay of all the other items combined
is only .5.
