The accf_http should flush out the oldest of these connections once
there are more than a certain number of them. I think that the
number permitted depeneds on the backlog parameter passed to listen.
I checked that this worked recently, and it seemed to do the right
thing on 7.X and 4.X. I'd be suprised if 5.X and 6.X differed in
a substantial way.
