O que costuma-se supor
A developer can mutate a `Set` from another task or nested call while iterating it and still get a consistent final result.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- Mutating the shared `Set` from another thread while `each` is running must raise `RuntimeError` with `can't add a new key into hash during iteration`.
- Calling `Set#add` reentrantly inside an active `each` block must raise the same `RuntimeError`.
- Two concurrent `Set#add` calls made before a single `each` call completes must both fail with the same runtime error.
