-//! Test if the OnceCell properly synchronizes.
-//! Needs to be run in release mode.
-//!
-//! We create a `Vec` with `N_ROUNDS` of `OnceCell`s. All threads will walk the `Vec`, and race to
-//! be the first one to initialize a cell.
-//! Every thread adds the results of the cells it sees to an accumulator, which is compared at the
-//! end.
-//! All threads should end up with the same result.
