Indeed, this is a major problem in so many ways it's not even funny.

However, considering the penetration of HTTP, it's not inconceivable
that we could get a couple of much needed extensions to the socket
API to stick, possibly as a "TCP considerations for HTTP/2.0"
informal RFC.

If there is interest in this, I can make FreeBSD one of the reference

One extension I have been pondering for a long time, is a true
per-socket idle timeout (Ie: no data-carrying packets in either
direction and no outstanding data to transmit for T time)


PS: And just in case some of you missed it, Queue had a couple of very
interesting spotlights on the dark buffer bloat issue some time
