It would be good to have an example that shows how to use these APIs to accomplish something minimally useful.
It might not be clear to the user what these APIs are for, what the parity of the barrier is initially, how to get the parity of a phase, etc.

| `barrier::wait_parity` stalls execution while the barrier is not at the specified parity. |

We should swap it to match atomic wait. Also make sense as we are waiting for phase to change

@wmaxey is this still relevant? Are these APIs still around? |
