* *A:* Runtime is wall clock time. A multithreaded demo can spend more than the wall-clock time rendering if the threads contend. * *A:* Runtime is wall clock time. A multithreaded demo can spend more than the wall-clock time rendering if the threads contend.
* *Q:* Using the C++ wrapper, how can I ensure that the `NotCurses` destructor is run when I return from `main()`?
* *A:* As noted in the [C++ FAQ](https://isocpp.org/wiki/faq/dtors#artificial-block-to-control-lifetimes), wrap it in an artificial scope (this assumes your `NotCurses` is scoped to `main()`).
