Notes from task review meeting: Needs to be done before launch. Hard-coded (or config variable) 15sec (or whatever) value in the code with a setTimeout() call/etc. in the outer node evaluator (not the Python/JS executor) and return a timeout error instead of output.

James's estimated effort: 0.5 day (if whoever picks this up thinks that will take considerably longer, please check whether we agree on the task)

Done. Note that we'll need to pass around the remaining timeout for clean re-entrant behaviour, but that's captured in another, post-launch ticket.
