Subject: long-lived tcp connection question

Given things like web sockets with presumably long-lived persistent
tcp connections and a sparse amount of data, I was wondering if there
are currently any mechanisms in the kernel or out of tree projects
which work on reducing the overhead these connections require?
Possibly storing their state after a certain period of inactivity and
then reviving them when work needs to be done? I'm thinking something
along the lines of the state info stored for time-wait sockets and
then the ability to resurrect it on an incoming packet. Keeping
resources around for such connections seems inefficient although
possibly unavoidable.

Thanks
Josh
