Nope - if they were backticks, you'd either get a NameError (if d and d2
aren't defined in the scope where the timeit calls are being made), or
you'd end up timing the evaluation of some string literals.

Mailer issues aside though, we still don't know where that initial set
of strange numbers is coming from.
