I looked into it and on my system (after temporarily disabling
FEATURE_ACCEPT_FILTER) the client side is always closed ~5 seconds
after the connection arrived and no data is sent at all.

This seems to confirm that it's a Firefox optimisation to keep
an open connection around just in case a new request needs it.
The ridiculous additional optimisation mentioned above doesn't
seem to be implemented (yet), though.
