> The call response buffer is allowed to dynamically grow until a max size is
> reached. Often times the full size of the response can be known in advance
> which avoids copies. This is very advantageous for large responses.
> Automatic framing of the response buffer will also prevent unnecessary
> allocations and copies when the size is/isn't known.
