Well, if you run the code for enough time (and ~25 seconds should be
plenty) then it's statistically impossible that you got unlucky
enough. And there's the usual thing with profilers: when in doubt,
run it 10 times...
(That "impossible" could probably be translated to a probability, but
I'm on the wrong side of the family for such questions...)

(I'm just wondering whether it would make sense to render via the
scribble/html bindings which might be faster.)
