Should now be sorted out for the moment.

We have this recurring problem where a single client can hog all the
download slots. Not using a lot of bandwidth, just taking up slots which
eventually means the number of slots hits the maximum and so no new
connections can be made. I'm not sure how other people configure apache
to avoid this problem. It seems like a really cheap DoS attack so other
apache users must get similar problems and so there must be a solution
somewhere. Sadly, I've not seen anything obvious.
