The answer would be a mix of A and B, mostly because there seems to be
an assumption that you have to consider concurrency everywhere in
order to be able to have it at some point later. This is not the case.

Thanks for your answers. Guess, I just got a little bit lost after
digging deeper into the whole thing. Just didn't see anymore that the
core problem is mutability. But it's much clearer again now.

See https://github.com/Raynes/clojail
It's a sandboxing library for Clojure, which among other things means
it needs to try running an operation and give up after N seconds. You
can skip the sandboxing part entirely if you want; it exposes a pretty
general thunk-timeout function.

Thanks in advance guys =)

I'd be interested. This doesn't really scale though in the way a recording
does. Are you thinking this would give you a chance to practice teaching it
before making a recording?
