By default `HeldCertificate` instances expire after 24 hours. Use `duration()` to adjust.

By default server certificates need to identify which hostnames they're trusted for. You may add as
many as necessary with `addSubjectAlternativeName()`. This mechanism also supports a very limited
form of wildcards `*.example.com` where the `*` must be first and doesn't match nested subdomains.

* Ler o corpo da requisição como um JSON.
* Converter os tipos correspondentes (se necessário).
* Validar os dados.
    * Se algum dado for inválido, irá retornar um erro bem claro, indicando exatamente onde e o que estava incorreto.
* Entregar a você a informação recebida no parâmetro `item`.

No OAuth2, um "scope" é apenas uma string que declara uma permissão específica necessária.

Não importa se tem outros caracteres como `:` ou se é uma URL.

Esses detalhes são específicos da implementação.

Para OAuth2 são apenas strings.

### Holding multiple locks

You're allowed to take the Http2Connection lock while holding the Http2Writer lock. But not vice-versa. Because taking the Http2Writer lock can block.

This is necessary for bookkeeping when creating new streams. Correct framing requires that stream IDs are sequential on the socket, so we need to bundle assigning the ID with sending the `SYN_STREAM` frame.
