Hm. And making this limit (and the listen backlog parameter) available as configuration options. :) Not letting bytes through is not enough, though.

Many people click on links before the server has finished (or before it has even visibly started) serving up pages. Searching the web today I saw a commercial product (I think it was a load balancer) promoting this as an important feature. Any page for which the client has closed the connection before the server has started serving up the page could be skipped. If the server has already started serving up the page, it could complete the transaction.
