The quantity of resources needed to hold a connection open but quiescent
while waiting for a timeout before sending another line of a response is
really quite low.

Yes, but spammers will always have fewer machines doing their end of the
job than the number of machines they're targetting. It only takes a few
more on the receiving end to do good response rate limiting and we can
slow down the spammers enough that they can't help but notice.
