Then again, there could be an execution limit to the parsing of a template.
We have one real-life example of this, of course, in the recent
template on es: Wikipedia that took 20 seconds to run and caused some
annoyance on wikitech-l ... how feasible are execution time limits in
practice, what's a reasonable limit (knowing people are going to push
as close to it as they can) and what's a reasonable failure mode
(knowing people are going to push as close to it as they can)?
