I don't dispute that it sometimes works today.

what I dispute is that makeing it work should be a contraint on a cleaner
design that happens to cause tcp connections to fail on suspend-to-disk
(hibernate).

if you are dong suspend-to-disk for such a short period that TCP
connections are able to recover (typically <15 min for most firewalls, in
some cases <2 min for connections with keep-alive) is it really worth it?

and once you pass the timeframes where the connections are still alive
then it shouldn't matter, and in fact the server should gracefully close
the connections to be nice to other devices and servers on the network.

I dispute the idea that doing a suspend-to-disk and expecting that your
network connections will recover when you wake up is a sane expectation.
