Technically possible. There are a few Scheme implementations that have persistent continuation (all I know is JVM based ones). Also this page contains a link to the slides that talks about persistent delimited continuation in OCaml: http://logic.cs.tsukuba.ac.jp/Continuation/program.html

Making continuations serializable may cost its implementation, so whether it scales well for yc.news is anothoer question. I don't know the answer for it.

In lua at least, continuations have a 1k stack overhead in memory per continuation. I believe they are serializable as well... I'll have to double-check that. At 1k+ a pop they're not cheap, but are manageable.

Having my tabs open last for a couple of days instead of 30 minutes would make the site more pleasant for me.
