The tests include:
- `TestBoundedForkedSync62`
- `TestBoundedForkedSync63Full`
- `TestBoundedForkedSync63Fast`
- `TestBoundedForkedSync64Full`
- `TestBoundedForkedSync64Fast`
- `TestBoundedForkedSync64Light`

None of these tests cover code that we use in production.
These tests were flaky upstream and eventually fixed.
No major changes to this codebase are planned before
deprecating it.
