Thanks all for the explanations, now my point is on the examples as seen by some first Wikidata users: if the examples are there and fail, that's disappointing. Have we to comment out examples that could fail ? Should we mark this ? I don't like the latter, but if it is a contingent situation it makes sense.
Till the work load is not managed, e.g. by optimizations, can we increase the timeout ?
