Actually you gave me doubt, so I made sure I was comparing
std::vector<std::unique_ptr<T>> with the other variants in my tests.
Now apparently I get roughly the same numbers as as boost::stable_vector<
optional<T>> in performance measurements.
Which makes me think my tests might be incorrect. :)
I'll take a closer look soon. I'm surprised using new directly is as
efficient as resetting an optional value.
